One of the Czerny opus 740 studies another poster has mentioned (Opus 740 has some very fun to play pieces). http://youtu.be/6e9iv9leq5k I've been working through the piece a bit and wanted to see how the lower third page section would sound if I wrote it into Sibelius (a sheet music program with a playback option). I struggle with understanding very simple concepts often, this gives me an extra way to study a piece. Anyway enough of that. The time signature is 2/4. The entire song has 16th notes running through, 12 per bar. (<is bar and measure the same thing?) This is where I'm stuck, with a 2/4 signature, it is only possible to have eight 16th notes in a bar(according to the music program). The study has 1 beat falling on each six 16th notes, but the 4 in the 2/4 time signature indicates 2 quarter notes per bar, or eight 16ths limited per hand. It would make sense to me that the 16th notes in fact are actually 24th notes (which don't exist that I know of) if written correctly within the time signature--but have been put in otherwise for convenience. I'm feeling very confused about what time signature puts 1 beat for 6 notes. I'm hoping someone here can make sense of my ramblings and explain simply enough so an idiot like me can understand =] thanks.
