Played on a Castagnari Giasco 1 D/G melodeon by Clive Williams, part of www.melodeon.net’s Tune of the Month Feb 2010.
Orange in Bloom is normally played as a waltz in sessions, or as a jig when played for Morris. It also makes a jolly good hornpipe though!
For those of you who haven’t met a Giasco 1 before, it’s effectively a 12 bass Castagnari Lilly, a single voice box with reeds mounted flat to give a concertina type sound. My one has unisonoric basses giving D, G, C, Am, Em, Bm all in both directions.
