In addition to the basic key configurations there are a number of other important variables which help determine the character of your instrument. For an overall view of the possibilities available to you, see the following list of options. If you require more information, please contact your Yamaha Handmade flute dealer. Mechanical Options C# Trill Key An additional lever and tonehole which are useful for B to C# trills, but can also be used to facilitate a number of other trills and tremolos. G/A Trill Key This aids in trilling from G to A. Split E Mechanism This key helps give more stability and better centered intonation to the high E. Clutch E Mechanism A switch allowing players to turn on or off the Split E mechanism as desired. C# and D# Rollers Rollers on the key levers to facilitate finger movements. Toneholes Drawn Toneholes Walls are drawn upward from the body material, giving the flute a broad, light sound. Soldered Toneholes Walls are soldered onto the flute body, producing a heavier, more solid sound. Soldered and Undercut Soldered toneholes with undercut inner edges give a strong sound with a lot of ‘life’ in the tone. Engraving Yamaha’s optional engraving is hand carved with unmatchable skill and care. The traditional Japanese engraving technique used has been passed done from father to son for many generations, making these flutes true works of art.
