Apparently you guys did NOT watch the Carol Kaye video. She shows you how it is done. First she said right out of her mouth, NO ONE in the 40s and 50s played scale tones. It was Chordal Tones. No one in the Jazz world sees it that way. Here is why, I will break it down for you what Carol Kaye is saying. First scales do NOT help you hear or see it better. The reason is YOU DONT HEAR the CORRECT CHORDAL INTERVALS in your ear. CHords are the EVERY OTHER NOTE of a scale. When you play scales you really DONT MOVE and you DONT hear the hills and valleys of your playing. Listen to Carol she is right on in the video. Second of all, learning the CHORDAL arpeggios allows u to play all the CHORD TONE patterns withOUT thinking about it and having to compensate lowering this and that in one isolated scale pattern. Plus Jazz music has BORROWED chords from many different keys. 75 percent of Jazz runs cycle and there is NO WAY a person is going to be able to react quick enough with scales over those chord changes. Scale people dont get it because they dont DEFINE the harmony right. Here is a test. Teachers will tell u that a C scale works over a C chord. BULL! Have someone strum a C chord or play it on the piano and then get a bass and play nothing but F notes or D, F, A notes. In THEORY its suppose to work and it doesnt because the F will CLASH against the E note of the C chord and the notes D, F, A over a C chord will sound AIRY, simply because the player had NO sense of CHORDAL tones viewing it from a scale perspective. Watch the video
You sort of hit the point and miss the point. The C scale over a C chord is not a literal thing, it a a reference, theory is a reference, and Carol is right what she says.....in her sitiuation. What we do is we learn more than is required so we can reference it.
Some call it chord tones......some call it scales, it is the same thing.
It is the same notes being referenced.
The C scale over everything is a reference, not a law.
Play a Cmaj. chord, alter it to a Csus4, now alter it to a C6, now add a 9 to that and alter it to C6/9, now alter it to Cmaj7, now Cmaj9, and finally alter it to Cmaj13.
To do all this you need to reference and use at some point the notes C D E F G A B C, those notes are easy to hear, easy to find and easy to reference...those notes are a C scale.
By the time you learn and add the other scales and learn about intervals, it becomes obvious what are chord tones and what are not, what can be passing notes and what can be "avoid" notes. All of this comes from having taken the time to learn more than is required, so when it is required it is there to referenced, then you realise music is note about scale tones its about intervals, then it becomes about syncopation, then melody, then melody within a harmony or a counter melody to a harmony, it becomes arrangment, it become..........well it is more than just should i just learn some of the notes available or learn them all.
Am i to believe that from the 12 notes we use in Western music that if i order seven of them a key, i should only learn four of them?
Am i to believe that if i learn three more notes, it will hinder me?
So if i do not need the 2nd, the 4th or the 6th note from a C scale, then what do i use for a 9th, or 11th or 13th?
Chord tones are every note of the C scale, it just depends how you order them for use.
