Which brass instrument is listed last in its typical order?

The tuba is typically listed last in the sequence of brass instruments due to its role within a standard orchestral or band setting. In the brass section, instruments are often arranged from highest to lowest pitch. The trumpet generally occupies the higher register, followed by the French horn, and then the trombone. The tuba, being the lowest-pitched brass instrument, comes last in this order.

In orchestral contexts, the tuba typically provides the bass foundation, contributing depth and richness to the overall sound. As a result, its placement at the end of the brass instrument listing reflects both its lower pitch and its supportive role in musical arrangements. The other instruments, while important in their own right, each occupy higher ranges and thus precede the tuba when considering their typical order in an ensemble.
