Altohorn: Wind instrument in the key of Eb (mainly), with an upward-facing bell, which fills the sound gap between cornets and baritone instruments in traditional brass bands.
Baritonehorn: It features a wider bore and produces a noticeably fuller, deeper, and warmer sound.
Flugelhorn: It looks visually similar to a trumpet but has a wider, conical bore that gives it a much deeper, softer, and darker sound. It is widely used in Jazz and brass bands.
Frenchhorn: The classic orchestral horn with circularly coiled tubing, a large backward-facing bell, and rotary valves. Available in single (F or Bb) or double (F/Bb) models.
Huntinghorn: Traditional wind instruments without valves (or with minimal rotary ones), featuring a large body designed to be carried over the shoulder. They produce only natural harmonic notes.
Tenorhorn: Instruments with upward-facing bells that cover the mid-bass frequency range of the band. The tenor horn has a narrower bore, while the baritone/euphonium is lower in pitch with a fuller sound.
