The sackbut, a Renaissance-era brass instrument, evolved into the modern trombone. The sackbut itself was a precursor to the trombone and was in use during the 15th and 16th centuries. Over time, modifications and improvements led to the development of the trombone as we know it today.

The transition from the sackbut to the trombone involved changes in design, including the addition of a slide mechanism. The slide allowed players to vary the pitch continuously, providing greater flexibility and expressive capabilities. This innovation distinguished the trombone from other brass instruments and contributed to its enduring popularity in various musical genres.

The modern trombone is a versatile instrument found in classical orchestras, brass bands, jazz ensembles, and various other musical settings. Its rich and resonant sound, coupled with the ability to produce a wide range of tones, makes the trombone a valued member of the brass family.
