Hi All,
I have been looking at the bass tab for 2112 and there are  extra letters above the tab that I do not know the meaning of (q Q w H e).
Can any one help as I cannot find an explanation for this?

Whole
Half
Quarter
Eigth
Sixteenth
Dots. next to these letters make the note 150% (3/2) of the original length; a dotted quarter will be the same length as a quarter and an eighth together

If you want to read more about rhythms, this might help a bit:

NeoMvsEu Thanks for that. Makes complete sense now you explained it Previously seen it with music staff headers in printed books but that's no use for a text file.
