Whenever I see a band advertising for a bass player, they always want either an EEb or a BBb. Rarely do we see an advert for a tuba player (in general) to join a section. Surely, as bass players tend to buy deeper and bigger rimmed mouthpieces and are expected to comfortably play in the pedal registers as well as occasionally using ledger lines above, the modern tubist should be able to play either EEb or BBb in the brass band? Some of the top bands regularly have had players utilise both positions successfully over the past decade or so! Are we stereo-typing the positions now because of tradition?
