Table 1

Characteristics of the seven tubas studied in this paper, classified in the same order as in Figure 1. By convention, the nominal pitch specifies a number of feet (ft) coupled with a musical pitch name, being the nominal fundamental of the instrument (lowest note playable without any valve depressed). The number of feet corresponds to the equivalent cone length , related to the frequency F_nom of its nominal fundamental by the formula , with c₀ the speed of sound in the air.
