Is the flute held sideways so the musician can blow across the top ofthe mouthpiece?

Yes, the Flute is held sideways, allowing the musician to blow across the top of the mouthpiece, known as the embouchure hole. This sideways position facilitates the production of sound by directing air across the hole, creating vibrations within the instrument. The horizontal orientation also enables the player to access the keys effectively while maintaining comfort and control during performance.
