Is there anyplace on the web that I can hear what your Big 18 sounds like? Do you have it in swing tuning?


Hello Patrick,

Yes he is in swing mooring. If you want, I can play some notes for you right and left hand and send it to you by email to let you discover its sound. I play the chromatic accordion, so I couldn't make you a piece, but I can make it sound (=;

Is there somewhere where I can see a chart of what notes are included on the Big 18 ?
