Q: what are the notes in the trombone train chords? a lot of HBCU marching band trombones play this https://www.youtube.com/watch?v=gNFB3qPvsHw
A: in this video, the first chord is Bb, Db, E (a diminished triad). the second chord is the same thing a half step up (C, Eb, F#). and the 3rd chord is like the same dim triad as the 1st chord, but add another note on top of the diminished totem pole if you will. so Bb, Db, E, G. some ppl call that a diminished 7th. in other words the whole deal is diminished stuff. i have actually never heard these fanfares i don't go to a lot of sports events
