Two questions: 1. I'm wondering how big the difference is between the importance of tongue level awareness between Trumpet players and Tuba players? I recently had a discussion with a great friend (who has a DMA in Tuba performance from ASU) about this very topic. He adamantly stood by his point that tongue level studies are not worth practice time for any brass player. 2. Is there a difference in the moisture content of slow warm air and cool fast air (Again, a point of contention in the above mentioned conversation) found in the breath used to play a brass instrument? Any thoughts on these? Thanks in Advance.
