May I add something for Valerie: If the leading player (concertmaster in the symphony or first fluegelhorn in the band) goes sharp a bit for whatever reason (room temp e.g.), one has to follow using the main tuning slide to adapt., no mater what´s ones own personal opinion or feeling. Listening to the other players is very important.
Said a wise music director to a player, who tuned his instrument according to his own feelings: "Buy yourself a stick & make yourself self employed, by founding & perhaps funding your own band !" ############################################################################## Am 21.04.2011 um 19:41 schrieb Jonathan West: > 1.
