I enjoy your piece. While it does sound good in general, I find don't hear a single C, nor did I hear one type of note type. I heard C# and G#, and you did lie about using only the note C. Suppose your could change your author comments?
Dear qwertyxp2000, thanks for listening ! Glad you enjoyed it. Do you have absolute hearing ? Or perfect pitch as they call it ? I think the synthesis of the sound messed up the usual diatonic scale here. I double checked; the piece does only contain the note C, well, that's how I arranged it. But the sound source is a modified sampled piano, hence the incorrect pitch. Didn't realize this was a way to create C# and G#. I have to rethink the names I gave to other pieces containing limited note sets.
