The YTR-9636 has a rich and attractive tone and is widely used in both solo and orchestral performance due to its natural ability to shift from C. It has a newly designed leadpipe with a unique shape. Transitioning between D and Eb involves changing the main tuning slide and first and third valve slides rather than by changing the bell.
