The second brass resonance mode is the lowest usable musical pitch

Evidence

The second mode is therefore the lowest musically usable mode avail­ able in a brass instrument (note that the lowest mode does not correspond with 1F). Overblowing from the second mode to the third mode results in a pitch jump of a perfect fifth, or seven semitones. — David Howard, Jamie Angus, coustics and Psychoacoustics, 1276

Categorization

• XREF: This connects to why brass instruments naturally jump fifths when overblown — relevant to the reader’s acoustic model building. — connects to: Brass instruments have no usable fundamental and start from their second mode — David Howard, Jamie Angus, coustics and Psychoacoustics, 1276; Musical instrument range stays below the auditory pitch-perception ceiling; Brass instruments differ sharply in how many harmonics their tones carry
