Hi,

I am working on a score for ‘Chi La Gagliara’ and am having a spot of bother with tempo ratios.

Where the score goes into 6/8 time, bar 22, there is a change of tempo indicated as:

[ a = b], where

‘a’ represents a quarter note and ‘b’ represents a half note.

Can someone please explain what this means in real terms.

Does the tempo speed up or slow down by a factor of 2?

Thanks.
