Whats vibrato and tremolo?
Confusingly, vibrato is sometimes referred to as tremolo. Basically, tremolo is variance in volume, and vibrato is variance in pitch. Tremolo is a regular and repetitive variation in amplitude for the duration of a single note. Vibrato is a musical effect where the pitch or frequency of a note or sound is quickly and repeatedly raised and lowered over a small distance for the duration of that note or sound.
