I would love to be able to sit down and just play my instrument and play music for hours, and express myself, but i reckon trumpet isn't the instrument for that.?.? Guitar guys can just sit and play for as long as they want without getting tired or losing their chops. I'm jealous of that. Is it impossible to just sit and doodle all day on the trumpet and sound good and not have to stop cause your tired or lose your lips. Ive only been learning for a couple of years, but is this even attaiable? Or should i change instrument?
