The Yamaha YFL-B441II Professional Bass Flute is a remarkable new instrument with special features that make it play easier and sound better. It is in the key of C, has a curved headjoint, gold-brass body, and a wooden handrest. New adjustment screws enhance its stability. A new scale improves intonation throughout, and especially improves response in the lower register. Gold brass construction makes the flute much lighter and easier to hold while still creating a rich and colorful sound.
