1000 BA to the winner (in Contests)

I played a game about 10 years ago that I want to find again...

It was centered on cavemen (i think) that composed music.

on the bottom of the screen was the sheet music. there was a jazz bassist. drummer and guitarist...


maybe im way off base here but i think a long shot like this deserves about 1k free BA.

It may not be exactly what you are looking for but here:

Now aside from that knowing the type (Comp, Console, Handheld etc.) it was on would be of great help in narrowing the options down. Aside from this I have found that the rendering style(CGI,Cartoon/Anime, Claymation etc.) helps a lot too. The theme wpuld help as well but Im thinking, from the description, it's a rythmn composer game but not exactly sure.

i was thinking about it this morning... it was kind of like spore only different and the music part wasn't the only part of the game... just the most fun.

definitely on PC or Mac.

I'm leaning on this one although it may be a bit older than what you stated. There are several in the franchise:
