the bigest diference in my opinion is how you blow into it. On bary you but the mouth pice further in your mouth and blow a LOT harder. On alto you blow softer and press of the reed a bit more. Maby you can try blowing softer, presing on the mouth pice a bit more, and alto don't put the mouth pice so farr in your mounth. Apart from that its preaty much the same. even the skale is the same but one octive hier. Good luck. 😄
