What is the sound source in a flute?

Answer 1

The wind you produce by blowing into the Flute.

As the wind passes the openings in the flute, the shape of the air is altered creating wave forms which can be interpreted as sound by the ear drums.

By pressing the keys and changing which holes are open you change the shape of the wind to form different sounds.

This is essentially the basis for all wind instruments, the final sound being the product of how many and which openings are in use combined with the type and shape of the material the wind is passing through all have an effect on the sound.

From this you get the basis for all wind instruments whether the flute, the Trumpet, the tuba or anything else you blow into.

You are simply reshaping the wind to produce wave forms.

Answer 2

Embouchure is your mouth's position on the mouthpiece of the instrument. A good embouchure takes time and effort, so carefully follow these steps to success:

1.) Hold the closed end of the head join in your left hand. Cover the open end with the palm of your right hand.

2.) Rest the embouchure plate on your bottom lip. Center the embouchure hole on the center of your lips. Check by touching the embouchure hole with the tip of your tongue.

3.) Gently role the head joint forward so that approximately 1/4 of the embouchure hole is covered by the lower lip.

4.) Keep upper and lower teeth spaced slightly apart.

5.) Draw the corners of your mouth straight back and relax your lower lip.

5.) Make a small opening in the center of your lips. Blow air partly into and partly across the embouchure hole.

6.) Practice regularly in front of a mirror. Roll the head joint in or out to find the embouchure position that produces your best clear and full tone.
