____ The Bolero is a Latin-based genre of music and dance known for its sensuality and intimacy; in fact, it's known to some as the second dance of love -- in addition to the rhumba, of course. But unlike the rhumba, bolero's origins are somewhat unclear and wildly debated. Some say that bolero originated as a Cuban dance that spread quickly to Spain; others say that Spain danced and played a version of the bolero long before Cuba altered the form. According to this idea, the bolero was created in Spain in the 18th century by the dancer and choreographer Sebastien Zezero. The form traveled to Cuba and by the mid-1800s had morphed into an almost entirely different form carrying the same name. The Cuban form of bolero is often thought to be the truest form of bolero, regardless of where it came from, and Pepe Sanchez's 1883 "Tristezas" is considered by some to be the first bolero ever formally written.
But regardless of who created what (and where), the bolero is an important element within both Cuban and Spanish culture, though the form is very different between the two. Cuban bolero is danced and played in 2/4 time and rooted strongly in African percussion. The bolero dance is very focused on couples, and the two dancers remain very close throughout the whole dance. Spanish bolero, on the other hand, is played in 3/4 time with a slightly less rhythmic undertone. The couples dancing Spanish bolero often dance apart (like modern informal fast dancing), only coming completely together at certain parts. Though the Spanish bolero style is still found occasionally, it is the Cuban style that gave birth to the various modern boleros still danced and played today.
Like most foreign music and dance styles, the bolero eventually found its way to the United States in the 1930s and became a sort of craze. As it shifted cultures, however, it underwent a few alterations. The American bolero shares more characteristics with the rhumba than any other traditional style, and it's slightly slower and far more intimate. Additionally, the American bolero was changed from the Cuban-based 2/4 to a slightly more relaxed 4/4.

What a piano players needs to know about a choir
At the risk of sounding obvious, there are certain basic things that piano players need to know as they deal with other musicians. If they lived in a vacuum they would not need to know stuff like this, but we and they just don't have that luxury.
The choir, a simple vocal ensemble of varying sizes (generally more than 10 people), is one of the most popular forms of musical expression for vocalists, particularly because of its availability in a varitey of arenas. The church choir is by far the most common, but many singers also perform in a high-school choir, a collegiate choir or a community choir. And within those varieties of choir exist a number of choir styles. There exists the all-female choir, the all-male choir and the mixed choir, which is comprised of females and males under the vocal categories bass, tenor, alto and soprano. Additionally, a choir can be classified by the number of members; a symphonic choir is typically a large choir while a chamber choir is extremely small.
Though some types of choir, such as the community choir, don't require much out of an audition (if they require an audition at all), there are certain traits a vocalist must possess in order to be able to handle the duties of choir membership. First and foremost, the choir member must be able to sing in tune; it seems common knowledge, but many would-be choir members are impervious to this ability. But singing in tune isn't enough -- choir members must also be able to blend their voice within the presence of other voices, to control vibrato and volume; the point to a choir, after all, is to hear an amalgamation of voices not one in particular. It is also vitally important that a choir member be able to read sheet music. An inability to read music will inevitably lead to the choir member never being able to learn his or her parts. Sight-reading, or the ability to read a piece of music without ever having seen it, is especially preferable for choir members, as a conductor will frequently ask the choir to sing through an entire piece immediately in order to get a sense of the music. Lastly, a choir member must have an independent ear; that is, they must be able to sing their part even while hearing a different part coming from the alto or tenor section. If a choir member has this problem and it's very slight, the conductor will usually place them in a position far from any imposing alternative parts, but a consistent inability to hear one's own voice will ultimately lead to a choir member having a difficult time with the entire performance.

What is a Chromatic Scale? What is a Chromatic Progression?
Most everyone knows what a major scale sounds like -- if you play all the white keys on the piano from C up to the next C an octave higher, that is the C major scale. You played all the white keys, but left out all the black keys. You played 8 white keys -- from the lowest C up to the highest C -- and you played a combination of whole steps (when you skipped a black key) and half steps (like between E and F, and B and C).
Now instead of leaving out the black keys, play ALL the keys from C to C -- black and white. Instead of an 8 note scale, you have a 13 note scale, and that is called a CHROMATIC SCALE. You could have started at any point -- not just on C -- and it would still be a chromatic scale. So a chromatic scale is entirely made up of half steps -- no whole steps -- you play every key, black and white.
A chromatic progression, therefore, is a chord progression that moves up of down by 1/2 steps; for example, from the C chord to the Db chord, or the F# chord to the G chord, and so on.

Where do you go to become a Professional Jazz Musician?
Where do you go to become a Professional Jazz Musician or work in the Jazz industry? Unless you have the talents of an Oscar Peterson or Amad Jamal or Bill Evans, you can go to school, the same thing you do to become a lawyer or a doctor. Don’t be fooled by thinking that because music is driven by creativity that education does not play a big role because it does. Having the proper fundamentals in music especially in your area of expertise is no longer optional.
Today there are many schools to choose from that have a Collegiate Jazz Program, almost too many. One of the finist is in Boston -- the Berklee School of Music, from which many jazz artists have come. Basically, you need to decide where you want to go and then start to research. Narrow down a list of criteria that you want in a school, and examine factors such as their job placement rate. Eventually you will find what you are looking for.
Depending on your ambition, you can go to college or university and achieve either a diploma, a bachelor’s degree, even a masters and PhD. You should enroll in a program that will provide you with what you need to be successful in your chosen career direction. Some of the careers available when you graduate from a Collegiate Jazz program are:
• Arranger
• Composer
• Conductor
• Copyist
• Orchestrator
• Record Producer
Schools offer real practical experience like co-ops and the chance to play live and perform in small and large ensembles. Each school will provide you with the opportunity to gain experience in collaboration and give you a networking foundation that you can rely on down the road. In today’s world prospective employers want people that have an education because it demonstrates that you have a foundation for learning in this field before they hire you.
School curriculums will offer many courses like composition and arranging, score analysis, jazz fusion composition and post bebop harmonic innovations. You have the ability to select what is most applicable to you and best of all most schools employ a faculty of industry professionals. There is nothing better then learning from someone with real industry experience and practical advice.

What does "SATB" mean?
For those who haven't grown up around choral music or in church, the term "SATB" might look like some strange code or an abbreviation for some government agency.
But all it means is: S=soprano A=alto T=tenor B=bass. In choral music there is a line of music for each part -- a line for the sopranos, a line of music for the altos, a line for the tenors, and a line for the basses.
The sopranos, of course, are the highest vocalists of the four, so their part usually is the melody -- the tune of the piece -- and is written in the treble clef. Right below the soprano line is the alto line, also in the treble clef, but lower than the soprano line.
In the bass clef the tenor part is on top, and the bass part on the bottom, in keeping with the vocal range of each type of singer.
If you look in a hymnbook (not the more contemporary chorus books) you will see there are 4 parts almost always all the way through the song. Those 4 parts are for the four vocal ranges we just mentioned: soprano, alto, tenor, and bass.
Piano players just starting out often play out of a hymn book just like it is written -- the trouble is, it was not written for a piano player, but for 4 different ranges of singers. That's why pianists need to learn what chord is represented by each stack of notes, from the bass up to the soprano, so they can then fill in and create a larger sound than they ever could just playing the singers parts.

What is a "Soprano"?
The term soprano is one of many vocal range classifications; it refers to the highest of all vocal ranges. To be considered a soprano, a vocalist's range must fall from middle C to a thirteenth above it -- though many soprano singers have ranges the extend far above that. It's generally a category reserved for females, though some males singing in a falsetto can be called soprano. Soprano singing is sometimes considered to be the most difficult and impressive type; whether or not that's actually true, the vocal quality found in a soprano is unlike that of any other classification.
Soprano vocal ranges can be further divided into several different categories. The specificity of these soprano categories is based entirely on the type of music being sung. In typical choral ensembles, a limited number of soprano categories is used; in fact, many choral ensembles will only use one, labeled simply as soprano. But in some cases, where vocal parts require further harmony, choral arrangements will utilize two categories: soprano I and soprano II. Soprano I is the basic soprano part, the part that would be present as simply soprano in a choral ensemble with just one part. Soprano II, also known as mezzo-soprano, is a bit lower than Soprano I, falling somewhere between an alto and a soprano.
Opera, however, is an entirely different ball game where soprano singers are concerned. Operas often contain no less than five soprano parts, all working on the subtle differences between vocal ranges. The highest of these categories is the dramatic soprano, or lead soprano, which is the voice that is typically associated with traditional opera. It's a type of soprano with an incredibly flexible range, one that extends far above the common soprano voice; for this reason, dramatic soprano singers are usually given the lead roles in operas. This type of soprano is so astronomical in range that it, supposedly, can break glass on the best of days; myth or not, that story clearly illustrates the sheer vocal abilities of a dramatic soprano, abilities that take years to hone.

What is an "Alto"?
The term alto is one of many vocal range classifications; it refers to the second highest possible vocal range. Just lower than a soprano, an alto range will typically fall from the E or F below middle C to the C or D an octave above it; it's the voice that falls between a tenor and a low, or mezzo, soprano. Alto singers are typically female, but it's entirely possible for a male to fall into the alto category. One a female, it's a voice rich and deep, one that is easily able to convey any sort of emotion. Though the soprano voice is highly coveted in opera and choral singing, the alto voice is very favorable in rock music or other types of popular composition. Karen Carpenter and Toni Braxton represent the allure of such a voice; they are two of the most famous alto singers in popular music.
Alto singers are often known for carrying the weight of the upper register in a choral ensemble. Though the soprano voice is responsible for the majority of a song's melody, the alto voice is what fills out the chord, creating the harmonies absolutely essential to a song's functioning. It's the kind of voice that sometimes goes unnoticed in a choral ensemble (most people hearing a piece for the first time seek out the primary melody), but one that holds the song together; without the alto voice, a piece would feel unfinished, nowhere near as full. As a result, most alto singers have a heightened sense of harmonic vocalizing; it's not uncommon for an alto to naturally sing a lower harmony to any piece of music put in front of them. This is a trait desirable in almost any musical group responsible for writing its own songs; the ability to harmonize and harmonize well is the very basis of an alto singer's craft.

What is "Figured Bass"? I, IV, V7, etc.
Figured bass is a type of notation that uses numbers to denote certain intervals or chords. It was used extensively during the classical period and is still taught in college music theory courses today.
It can be viewed as a sort of musical shorthand; only the bass note is shown on the staff, and the numbers written underneath indicate the general idea of what should be played. Figured bass is very similar to Baroque era's basso continuo, a type of minimal notation given to accompanists. The accompanists working with the basso continuo or figured bass knew the basic structure of the song but had to rely on improvisation to complete the entire piece. Improvisation is important here because figured bass only indicates the song's harmony; the rest is decided by each musician, depending on the style and tone of the music and the other instruments involved.
The figured bass notation is based solely on the bass line. The bass note is shown on the staff, as usual, but underneath are a series of numbers. These numbers in figured bass notation denote the intervals with which the chord is to be played; any accidentals are written next to the numbers. For instance, if an F is shown on the staff with a four and six underneath it, the figured bass notation is telling the musician to play an F chord with notes a fourth and sixth above the F. And if that four, for example, is shown with a flat sign, the figured bass is telling the musician to play the fourth a half step down.
If the chord contains a third or a fifth, however, these numbers are often omitted from the figured bass. A third and fifth with any bass note creates a triad; the sheer commonality of triads led those using figured bass to get rid of the numbers and simply assume their presence. Likewise, if only one number is present underneath the bass note, figured bass assumes the missing note to be a third.
Even the bass notes themselves are sometimes left out of the figured bass notation to keep the shorthand truly short. If a bass note repeats itself for several bars, only the first instance of the note will be shown in the figured bass; after that, the only thing to denote the chord will be the series of numbers. Until it changes, the bass note here is completely assumed.

What is a Ballad?
In the world of jazz, a ballad is a slower piece, sometimes very slow, where the soloist often falls way behind the beat to make a point, and then at some point catches up. Some of the great jazz ballad singers were June Christi, Sara Vaughn, Billie Holliday, Shirley Horn, Nancy Wilson, Nina Simone, Diana Shuur, Anita O'Day, Diana Krall, and of course the incomparable Ella. They sang many other styles as well, but in my book, nobody sang ballads like these gals.
Outside of jazz ballads are an increasingly common musical concept in modern popular music. They're generally thought of as slow, highly melodic songs that tell of some sort of heartbreak; there's even a whole CD dedicated to power ballads, the result of heavier rock bands taking it down a few notches to tell about love gained or lost. But true ballads, in the strictest sense of the word, are far more complicated than just taking a song's tempo down by a few beats per minute. True ballads date back to way before heavy metal or modern folk music. True ballads are an integral part of historical folklore.
Ballads are songs that tell a story, like poetry or folk stories set to music. The stories told in ballads tend to be well-known and oft-repeated and often incorporate tall tales. Increasingly, however, ballads have been adapted to the plight of the everyman; ballads are the peoples' music and will always tell about the people of that particular time.
Ballads are distinguishable from other types of songs by a few important characteristics. The lyrics in ballads tend to focus far more on action than reaction and will usually be sung in the third person, like many literary folk stories. Ballads also tend to focus on the song's lyrical (as opposed to instrumental) qualities; since a ballad is focused so heavily on the story being told, it's vital that the lyrics get first billing. Because of this, the lyrics tend to be simple and easy to repeat. The chorus, especially, must be memorable; it was designed specifically to be sung in unison by the audience, many of who will have only heard it once. This memorable quality is vital also because ballads, in the truest sense of the word, will almost always have been passed down from generation to generation. The ballads will certainly evolve over time, but the basic elements of story will remain in tact.
Because true ballads tell folk stories, it's not surprising that ballads have remained a large part of the folk music genre. But even in that most integrity-based area of music, ballads haven't always maintained their essential elements. The notion of ballads, just like the ballads themselves, has evolved so much over time that the ballads of today barely resemble those of the original criteria. Still, despite their differences, they are still considered ballads -- just in a much looser form (consider the modern ballad "American Pie"). Power ballads, on the other hand, can hardly be called ballads, even by those who allow the word to be very loosely interpreted. Power ballads rarely fit any of the criteria of original ballads, other than the frequently found subject of a lover scorned. No matter how slow, melodic or heartbreaking certain songs are, they can't always be called ballads; a catchy chorus does not always a ballad make.

Acoustic Pianos
The term acoustic piano is a fancy, more descriptive way of referring to a normal piano. It's typically only called an acoustic piano when being mentioned in conjunction with digital or electronic pianos; without those barriers, the acoustic piano needs no distinction. It is, simply, a piano. It comes in various forms, some better than others, and is usually considered a part of the percussion section; an acoustic piano has the potential to drive the rhythm just as effectively as the drums.
One of the most startling facts for a music-loving child to learn is that an acoustic piano is actually a string instrument; growing accustomed to violins and cellos as rote for the string section, it seems so unlikely to us as children that an acoustic piano could fall in that category. An acoustic piano produces sound by a series of strings stretched on a frame; the strings on a grand acoustic piano are stretched horizontally, producing a thick sound, while the strings on an upright acoustic piano are stretched vertically, tending to make the sound more tinny. The keys on an acoustic piano are attached to tiny hammers; when triggered by pressing a key, these hammers hit a string and produce that familiar acoustic piano sound.
An acoustic piano consists of a large wooden frame enclosing the strings and pedal mechanics and a keyboard which is used to actually play the instrument. The keyboard generally has 88 keys (though sometimes less or more, depending on the manufacturer), each of which corresponds to a specific pitch; these pitches are named after the first seven letters of the alphabet and retain that name regardless of the octave. The 88 keys on an acoustic piano hold roughly seven octaves with the lowest octave starting to the left; the white keys represent the seven natural notes of a diatonic scale, and the black keys function as the accidentals.
