Quick Summary

In music, "overblowing" refers to forcing too much air into a wind instrument, which can produce undesirable overtones that mask the fundamental tone. This technique is used to play higher notes in an instrument's register.12

For instruments like clarinets and saxophones, overblowing typically occurs at the 12th or octave, respectively. For trumpet-type instruments, overblowing is a process where increased breath pressure causes the air column to divide into smaller segments, producing higher pitches called overtones or harmonics. These overtones are part of the harmonic series, which theoretically extends infinitely.23
