What term, more masculine than falsetto, refers to the optimal combination of airflow and glottal tensions that yields maximum vibration?
Falsettone Falsettone is a term used in modern Italian musicology to describe a vocal technique used by male opera singers in the past, in which the fluty sounds typical of falsetto singing are amplified by using the same singing technique used in the modal voice register. The result is a bright, powerful tone, often very high-pitched, although the sound is still different from and more feminine than what is produced by the modal voice. The term "falsettone" is also used for the mixed vocal register that can be achieved using this technique.
Tuba The tuba ( or ; ] ) is the largest and lowest-pitched musical instrument in the brass family. Like all brass instruments, sound is produced by moving air past the lips, causing them to vibrate or "buzz" into a large cupped mouthpiece. It first appeared in the mid 19th-century, making it one of the newer instruments in the modern orchestra and concert band. The tuba largely replaced the ophicleide. "Tuba" is Latin for 'trumpet'.
