Which instrument does NOT belong to the band’s standard instrumentation?

The tuba, while a brass instrument commonly found in many musical ensembles, does not traditionally belong to the standard instrumentation of a concert or marching band in the same way that the other listed instruments do. Concert bands typically include woodwinds and brass instruments to create a balanced sound, with the trumpet and clarinet providing key melodic and harmonic contributions. The saxophone, although a relatively newer addition compared to the trumpet and clarinet, has become standard in many band formats due to its versatility and range.

In contrast, the tuba, while it does play a crucial role in providing bass lines and depth in orchestral and concert settings, is often not included in smaller band configurations. In a standard concert band, the instrumentation usually emphasizes a mix of woodwinds and higher brass, which is why the tuba is less common compared to the other options presented.
