RE: An Interesting URL for All You LD Jazzheads Out There . . .
Title: Message
Very
cool, Ted. It really illustrates how difficult it is to improvise over that
tune. A friend of mine, Mark Levine, has a book, "The Jazz Theory Book"
that provides a lot of analysis like this. In fact, page 352 of that book breaks
Giant Steps down into further details of these tonal centers: I chord in B, V-I
in G, V-I in Eb, ii-V-I in G, etc, etc. It's basically taking the
standard ii-V-I format of jazz standards and turning it into one butt kicking
tune. That song scares the hell out of me. I've only played it as a ballad
live, never at 300 bpm. At least Giant Steps is analyzable like this. Other
more modern jazz tunes, such as by Metheny, Pat Martino, Jaco, etc...are crammed
full of slash chords, synthetic chords, polychords, etc, which make it difficult
to find the tonal centers.
I
think there could be a program that does what you ask. It would
have to look at the song as a whole and make some decisions on chord functions
based on pre-defined criteria. For instance, a minor chord followed by a
dominant chord is probably a ii-V in most jazz charts, but it could be the ii
chord of one key, and the V chord of another, or it could be a ii chord in
one key, and a secondary dominant chord in the same key. I bet the program
would do well with most of the tunes in the standard Real Books. Analyze
the head melody over the chords and it becomes easier, because the melody will
provide hints on chord function.
Thanks for sharing! It was fun watching
that.

p.s.
I just blew the dust off of some clips of me playing some cover and
original jazz tunes. The cover tunes are Goodbye Porkpie Hat (by Mingus)
and Footprints (by Wayne Shorter) live...Goodbye Porkpie Hat is another
tune that has some interesting tonal centers. The other three are
originals of mine. I added the sheet music to one tune, if anyone wants to
try it out!
Hi Ho!
A jazz guitarist friend of mine that i used
to work
with/for sent this the other day. Its a URL for a
website that
diagrams the tonal centers of
Coltrane's "Giant Steps" in real-time. Check
it
out. It's very interesting.

Wouldn't it be
really, really cool if there was
a computer program that could "listen" to
any
live musical input and similarly diagram it?
