Below is how to hold the recorder to make the first note E on the
Yamaha Alto Recorder YRA-314BIII
A : The first finger of the left hand closes hole 1
B : The left thumb fully closes the thumb hole
C : Only the tip of the mouthpiece ( beak ) touches the lips. Do not put the mouthpiece into the mouth
Try to shape the mouth to silently make the sound "TU" and blow into the recorder, but do not voice the sound. Do not make the TU syllable explosive. Make it gently.
Start every blow with the sound "TU", and continue blowing.
Articulation helps to control the breath and also provides a distinct start to the note.
Do not blow to hard. The alto recorder needs very little air pressure. So relax and blow gently.
