trumpet
Trumpet produces a higher pitch as compared to a Trombone
Between those two, the trumpet plays higher.
Strictly speaking, the trumpet has a high pitch, however the highest note that can be played depends on the ability of the player.
The trumpet in general is a higher pitched instrument because it is smaller and has less tubing.
A trumpet player will probably be able to make a sound on the trombone, but a lack of skill in using the relatively large mouthpiece on a trombone will result in a low quality sound at best. Plus, playing a valved trumpet will usually not make for an easy experience trying to learn a slide trombone.For a bit of fun, ask a trombone player in your band if you can try his instrument out. Try using your trumpet mouthpiece to see what it's like.
The trumpet is the higher-pitched instrument of those two choices, because it's smaller.
