Now, I have been classical trained for a reasonable amount of time (Four? years total), but have stopped lessons for about 2-3 years. Now, I want to learn improv jazz. What I want to know is this: Is it easy, even for somone at my level to learn how to do? How is it done? (basics) Are there any free sites I can use to learn by or use as reference or help? How long does it usually take for an adverage someone to learn it to an adverage level?
This is a good question.
(1)It is easy if you really desire it. You will keep working on it.
(2)There are myriad approaches to it. I’ll give some easy starters.
(3)I don’t know of any free sites to help you but there was a series on vinyl records called "Music Minus One" that has been continued by Jamey Abersold on CDs. Google him. (These are recordings of a jazz band playing songs with "one" instrument out of the mix. For instance, piano. You play along with the CD. Most of the recordings have the entire group playing the song also on the CD.)
(4)You can start immediately at an average level.
Here’s what to start with:
(1) The chord structure of the song is all-important in most improvisation, so you need to know the song well. It is best to start with a simple chord pattern or any short pattern you know well. One of the most basic patterns is the "blues"– 4 bars (measures) of the I chord, 2 bars of the IV chord, 2 bars of the I chord, 1 bar of the V chord, 1 bar of the IV chord and 2 bars of the I chord. (If you don’t know the roman numeral system, they are just referring to the first, fourth and fifth tones of whichever scale you choose. For instance, in the key of "C" you would use "C", "F" and "G" chords. In basic theory the one chord is a major triad, the four chord (F) and the five chord (G) would be dominant 7ths (the first, third, fifth and flat seventh tones of the chord’s scale). This is the standard "12-bar blues form and there are many variations. Don’t worry about these finer points at first, just get the pattern down.
(2) If the chord pattern doesn’t bring any "melodic" line to your mind, pick any short (one bar long, for instance) rhythmic or melodic motif that you like. For instance, a group of three eighth notes on the fifth tone and a dotted quarter on the first tone followed by a half rest to fill out the measure. On the "C" chord this would be g-g-g-c (I would go down to the c but it doesn’t really matter.) On the "F" chord it would be c-c-c-f and on the "G" chord it would be d-d-d-g. Now this is just an example of a motif to use within the chord structure. I picked it at random to show how the tones of the scales are used to improvise upon the chord structure. You could use a more complex motif such as five-four-three-four-one in any rhythmic pattern which appeals to you. Or anything! Just choose something and play it across the chord changes. You are "improvising" a melody on top of the chord structure.
(3) Once you get the hang of playing on top of the chord structure try different motifs and mixing different motifs together. Or try playing a motif on one note throughout the chord changes (for instance a quartet of 16th note "c" notes every other beat through all the chord changes–stay on the "c" note. Another thing to try is "quoting" a line from another song on top of the chord structure–for instance just the six-note "happy birthday to you" or the 4-note "here comes the bride". Use anything that comes to mind, but fit it into the chord structure
(4) That’s basically all there is to it. You improvise a melody line on top of the chord structure. When you get really good at it, you can do it "in real time". Most of the improvisation you hear recorded is rehearsed and worked out ahead of time. It may not be written out note-for-note, but the player has some plan in mind. If you listen to live jazz, you might hear some purely free improvisation. It is indescribably wonderful when it comes out right– for the audience and for the player!
