This flute is made from a composite material which is super light-weight, and is actually lighter than the standard Grenaditte flute. The sound is brighter and much like that of a regular metal flute. Note: The Grenaditte Flute has a sound closer to that of 'wood' rather than 'metal'. This New Voice model comes as standard with open holes and B footjoint. It has an ergo-friendly G# key. The flute is able to produce a very strong, robust sound in all registers and plays low C and B effortlessly. Great idea if you plan to play outdoors as it is waterproof!
