Another question. It would be also useful to have a function that increase the tempo by a certain quantity (instead of a certain factor). 

I tried to modify the previous code in many ways using moment-add and make-moment but without success. This is an example that does not work:

(ly:moment-add (ly:context-property c 'tempoWholesPerMinute) value)

 

Any suggestion?

Thank you, G.
