This will be difficult for me to describe, but I`m giving it a shot. I`m trying to find the name of this song I heard and possibly some sheet music. I heard this little section played by a jazz/jam band, but I know it`s from a classical piece.

From what I have figured out, it begins like this:
G (1/4), E (1/8), F (1/8), G (1/4, E (1/8), F (1/8), G(1/4), A-B-C-D-E-F (all 1/8), E (1/4), C (1/8), D(1/8), E (1/4), C (1/8), D (1/8), E (1/4), E-F-G-A-B-C (all 1/8), B (1/4)... from here I`m having trouble figuring it out, especially since I don`t know the name of it to listen to it. My directions certainly aren`t the clearest, but you should recognize the sound pretty easily. I played it on piano to figure it out, but it was played on both guitar and violin by the band.

Any help would be greatly appreciated.

could you say what the time signature was? i think i possibly might no it

I believe it is in 4/4 time.

Sorry about the confusing notation, I can`t really figure out another way to type it out. By the way, the A-B-C-D-E-F thing starts at the A an octave BELOW the original G.

Also, the next phrase is similar, except it starts at the E an octave below and goes: E-F-G-A-B-C (all 1/8), B(1/4), G(1/8), A(1/8), B(1/4), G(1/8), A(1/8), B(1/4), G(1/8), A(1/8), B(1/4), D(1/4), C(1/2). At least that`s what I recall, obviously it may not be perfect - but you ought to recognize it.

Thanks for any help.

Is it "Cannon in D" by Pachelbel?

that`s definitely canon in d by pachelbel, either you or the jazz band have just transcribed it into c.

canon (as previously stated)
