Yamaha´s unique expertise with the various alloys used in brass instruments has led to the discovery that gold brass (brass with a higher than usual copper content) is the perfect material for optimum tone, weight, and playability. The gold brass gives a rich, colorful sound, and the flute is much more comfortable to hold and play than traditional alto flutes, being considerably lighter.".925 solid lip-plate and riserGold brass headjoint and bodySilver-plated mechanismStraight headFrench-style 'pointed' key-armsIncludes case, case cover
