@stereoid, hopefully this should explain things a bit:
numbers like 1 and 7 are used to represent notes within a scale. So on a C scale, C is 1, D is 2, E is 3 etc. etc. They're used to make transposing songs and chords in your head just a little bit easier to comprehend--and even communicate.
So, when I say:
Quote:
put the 3 and 7 in the left hand (I[7]) and play a D chord in the right (II).
|
on your C scale your going to put your left hand on E and Bb and play a standard D chord (which would be D, Gb, and A). Now if you have someone play a C note on a bass or even the piano, you'll come out with a C7 flat 5 chord.
Hope that explains a bit.
peace,
