You got my attention, also.
This is one of my struggles, hearing the patterns in a song. Most of the time, I can't hear the keys in the songs because of all the other instruments. Any suggestions?
I also struggle alot because my ear still needs alot of developing.
But it's not so much the patterns I struggle with..It's hearing the actual tone/ voice I want to hear if it's in a song.
Sadly, I don't know of any other way of hearing the "voice/ instrument" other than actually listening to a cd over & over again, trying to screen out the other instruments (so in a generic song, it would be the brass/ horns you want to screen out, as well as the bass if you have a bass player).
In the case where you don't have a bassist, then try to listen for that bass..This is normally the easiest tone to hear.
You could also use the bass to find your key.
Sometimes, in fact, most of the time, the pianist will be playing some intimidating stuff
In this case, the best is really your best friend. Follow the bass line & try to listen to how it sounds when you end a verse or hit some ending: does it sound tonal?
Most songs have verses that end on the "1".
Also, the bass gives you a nice spine of the song..(take a preview of Brighter Day by Kirk for instance..those horns are intimidating..but the bass can be caught onto with some (or lots) of effort..)
Do you notice what I've just said effectively here...
I've actually said what T-Block always says: use the bass to give you the direction of the song..then you can fill in the chords that go with it (can be strenous!!)
So how do you make identifying the bass & predicting the bass patterns even on a song you've never heard before easier?
--going up or down a half step is quite popular.
eg, up: 1->#1-->2 or 5->#5-->6 (eg in key of CM: C->C#->D; G->G#->A
eg, down: 6-->b6-->5 (note, this is very common..here, the "b6" is played to take you to the "5" instead of the "2".
had you played a 2, it would have been a 6-2-5..& notice how that 6-2-5 is moving in 4ths...
so in the key of CM: 6-b6-5 = A-->Ab-->G & the 6-2-5 = A-->D-->G
I mentioned "predicting the next note" above, right..
So can you predict what's the most likely bass note to come after the 5??
of course you can What I've just explained above might seem little, but taking some time to listen to those progressions I've just highlighted above & being able to at least recognise them in a mid-tempoed song will take you far.
You should even start to sing in numbers (I did it alot when I was learning all the other keys & do it occassionally..I always do it subconciously!--Have U seen Kevin "KC" Conley's preview.. he was doing it for "No Weapon!")
that's end of step 1.
step 2 is figuring out the chords.. some gurus can explain how to go about.
oh, almost forgot...
to help you out with the 2-5-1 pattern :
there is a song by R Kelly titled "How Did I Manage"..in the key of C..
the bass pattern from start to end is 6-2-5-1...
What I did with it was to play the alternative bass patterns over it, ie, play 6->b6->5->1 [A-Ab-G-C] instead of 6-2-5-1 while the song is playing.. sometimes I played 1-#1-2 instead of the 1-6-2 (see that pattern there since the bass just rotates like that..
& then of course you play the pattern as a 6-2-5-1 other times & variate..listen to the variations..
As for the piano part, lots of improvising taking place there, but the bass note sort of gives you an idea of how to improvise.
that's where I stop. (please find the song on youtube or somewhere else..) gotta go to church.
