Hi Fran,
Here's some additional help, perhaps. I have a very good quality metronome. It says:
Largo 40 - 60
Larghetto 60 - 66
Adagio 66 - 76
Andante 76 - 108
Moderato 108 - 120
Allegro 120 - 168
Presto 168 - 208
I like ranges of tempi rather than a single, solitary number. I play music within the ranges above usually, but I also take liberties by slowing or speeding up the tempo outside the recommended range for effect if that is the direction my mood or musical taste takes me.
Hope this helps.
Take care,
Chuck
