I did play alto sax for a while a couple of years ago, and I was told that the embouchure was similar if not the same as on clarinet.
Presuming I already know the fingerings for clarinet and therefore bass clarinet (Clarinet Fingering Charts - The Woodwind Fingering Guide if anyone wants to know), would knowing the alto sax embouchure be a good start?
I really want to take up bass, but I really really don't want to have to learn soprano clarinet beforehand.
