It probably relates to composers using electronic sound libraries to preview their work. An electronic trombone sound is not constrained by the abilities of the instrument and thinks nothing of, for example, a gliss (portamento) from D3 to G3 (both of which occur only in 4th position separated by one partial).MStarke wrote: ↑Mon Sep 23, 2024 7:34 am Another one: (Contemporary) Music with trombone parts that don't even theoretically make sense on trombone. Impossible slurs, parts playing in extreme high or extreme low ranges, extreme especially soft dynamics that would better call for using a mute to reach the effect. All things that might even musically make sense, but don't consider feasibility. Especially if these pieces are being premiered by amateur organizations.
I have one of these coming up (subbing with an amateur orchestra). Will be interesting to see how it works out.
I think it makes a huge difference if you write that sort of thing for a specific group, a top pro orchestra or a specific soloist or if you write it just for a random orchestra.
A composer who studied the capabilities and characteristics of each instrument would avoid some of these inexcusable errors.
