Normally flutes come with a foot-joint to low C (front right – two pads) – sometimes manufacturers offer an option buy one that goes down to low B, meaning there are then three pads on the single foot-joint. A low B flute will naturally happily play low C, so doesn’t normally come with two foot-joints – at least not any I’ve seen.
But this flute, going down to low Bb – uncharted territory for most flute players – has one foot-joint to low C, a second one to low B, and a third foot-joint (front left) with four pads down to low Bb.
Can anyone tell me why three foot-joints are necessary – OK, I can possibly imagine one to low C, and maybe a second one to low Bb for special occasions. After all, playing normal music, who wants the extra two hole length adding to the balance (or lack of…). But three foot-joints ? All that unnecessary engineering, and cost !
