Most of my music is improvisation, and composition is improvisation. Even if I have a score, it is improvisation.

I don't think I differentiate between composition and improvisation. Improvisation could be a large part of a composition.

For a long time in the 1970s, I was experimenting to build musical instruments and use them. I did a lot of ethnic music studies and other things, like electronic music. Making homemade musical instruments and performing was my major activity from the time.

I got into one of the Scottish classical styles called piobaireachd, which is a very old music that started around the 1700s or something. I really got into this music. After that, I started to compose bagpipe music in my notations. Then I started building bagpipes by myself, and then I started to perform with the instrument myself in the 1980s.

I remember, in elementary school, being asked what my father does and not knowing how to answer. When I asked my mom what I should say next time, she replied, "Just say he's self-employed." I love that.

Scottish bagpipe has two tenors and one bass - three drone pipes - and then the one chanter. If you put bagpipes together, it creates such a fine sound.
