I have been learning to play alto sax for the past couple of years and I'm quite happy with tone production in the middle and to an extent, the high register. However, I have an issue with the low register.
I can play the low B flat and low C, but the low B sounds exactly the same as low C.
I'm pretty sure I am fingering it properly but have attached a few images below that should show what I am doing.
Does anyone have any suggestions?
