Gallay’s 6 Easy Duets Op.41 for Trumpet or Horn is an interesting collection. It is possible that back in Gallay’s time these were “easy” but today I would consider them to be intermediate level, if for no other reason than they go above the staff in the first few measures.
These are taxing but very interesting, technically challenging but also fun to play. These are ideal for studio use, trumpet hangs, masterclass performances, and so much else. Grab your horn and try out the samples then grab an immediate PDF download above.
