Piccolo trumpet - Sound characteristics
The piccolo trumpet has a sound which exhibits all the typical characteristics of the trumpet, although it is brighter and clearer than the C trumpet.
The sound is particularly homogenous in all areas and it is not necessary to differentiate between registers since there are no noticeable abrupt changes in timbre between the powerful notes in the lower register and the sharp, strident high notes. The instrument’s easy response means that the full sound is achieved immediately after blowing. The sound develops best between C5 and C6.
