YFL-617 YAMAHA Professional Flute [FINESSE]

https://www.suitupmaine.org/yn5wn13khhu Because the covered keiki cup has a lid shape, the key holds the hole securely and prevents leakage of breath.The covered key model is easy to hold down naturally by combination with an offset key (G key which is operated by the left hand finger and protrudes, finger length matching arrangement).

https://www.suitupmaine.org/kfqpfq8b6 Technique is needed to hold the hole reliably because the  ring key ring cup is ring shaped, but because you can feel the vibration of the air directly at the fingertip, it is possible to control the nuance of fine sound. It is also attractive to have a high degree of freedom of pitch by operations such as shifting fingers. In the ring key model, the combination with the inline key (the key of the main pipe is arranged in a straight line) is common, but you can also choose the model of the offset ring key.

The E mechanism is a key system to make it easier to output "M" (E sound) of the third octave which is difficult to put out due to the structure of the flute's flute.

In addition to the model with C foot pipe (C tube: "D" is the lowest sound), you can also choose a model with H foot pipe (H pipe: "S" is the lowest sound). H foot tube can play not only the sound of "shi", but it may also be selected from the tone preference that changes as the tube becomes longer. C tube flute is bright and shining tone color, H tube flute is dark and glossy tone color. Also, in the H tube, the bottom key is sometimes used alone to stabilize the pitch in the high range, and Yamaha's "Gizmokyi" for such a case is equipped as standard.
