I've been playing lever harp for 25 years now, but a cross-strung harp will enable me to play more sheet music written for piano!
They're around 3000 euros.
I play harp, koto, recorder and tin whistle, write sheet music and make illustrations.
On my Youtube, I'll be posting harp/flute videos and Synthesia videos.
My commissions are for illustrations (though I can also write arrangements for the above-mentioned instruments and choir).
