I am a trombone player, so I haven't used it much. -------- Quartet collection for French horn, edited by Heinz Liebert. - Title: Wald Horn Quartette - Instrument: French Horn - Arranger: Heinz Liebert - Volume: Volume 1 - Key: Horn 1 in F - Key: Horn 2 in F - Key: Horn 3 in F - Key: Horn 4 in F Thank you for looking.
