The YFL-B441 bass flute is made from gold-brass like the YFL-A421 alto flute and features a similar quick response, rich beautiful tone, and accurate intonation. The bass flutes are often used in flute ensembles and studio recordings, and are increasingly used to play difficult alto solos in the orchestral literature. As with the alto, the gold-brass makes the flute much lighter and easier to hold, while still creating a rich and colorful sound.
