the notes are A, B, C. those are the 2nd, 3rd, and 4th scale degrees of the G major scale. or the 1st, 2nd, 3rd scale degrees of the A minor scale. you are right, though, that this could also be some notes from a C major scale or an E minor scale. good sleuthing!
Hi! My name is Christopher, and I used your audio in a short stop motion clip my son and I put together. I gave attribution in the info section. The video can be found here: http://youtu.be/J7upJkhm6Gk
Please let me know if you would like a more specific name attribution or don't want your name on it at all! Thanks!
