Here are a couple more piano tunes I wrote a while back while I was tinkering around with the fugue style.
In a 3-voice fugue, the main theme is introduced in the first voice, then repeated an interval above with the second voice enters, then again below when the third voice enters. In most cases, after the voices finish their themes, they go off and do their own things for a little while (actually with some variations of parts of the theme) before the main theme comes back again at the end.
I chose a different instrument to record these (other than piano) mainly because I liked the sound of it.
