Recently my friend, Rien Schalkwijk,played a Basse de Trompète and I remembered how much I loved them (I do enjoy a lot of French classical repertoire!). In keeping with the last piece of French classical repertoire I played by Dandrieu, I've put together three Basse de Trompète's (A minor/D major/A major) for you here on the magnificent sample set of Rotterdam, by Sonus Paradisi. This instrument is versatile enough to do justice to this pre-Bach repertoire. I've left a link to Dandrieu's first organ book below. Thank you!
