The trumpet range may be displayed in the treble clef as shown right.
The notes shown in the example above are the written notes and logically on the B-flat trumpet the notes sound a tone lower. On the D trumpet, the notes would sound a tone higher.
On the B-flat trumpet, any notes up to the highest G can generally be produced with great confidence and surety either very quietly down to ppp or very loudly up to fff. The very top notes up to the highest C should be very carefully utilized. They can be brilliant in effect but straining on the ear if overused. One point worthy of note is that the C trumpet may be said to have many advantages of tone quality and intonation over the B-flat trumpet in the highest register. For a time this fact caused the C. trumpet to present a serious challenge to the supremacy of the B-flat instrument.
