SUITABILITY/PERFORMANCE

OVERALL OPINION

I use Crescendo for 3 weeks, not trsrgulirement lack of time, even if I know I should do more to advance.
I find the software trs well done (although I have no point of comparison with other programs), reading the floor and cl cl fa, hearing, recognition of intervals, ryhtme , etc ...

There is a balance which allows space to see the progression of the lve ds DIFFERENT surrounding areas.

What I like least: the "sound" quite strident notes.

It can not replace a teacher solfge but it is a good complment trs. A friend who is the piano for 4 years bought the "Pro" version (which covers 8 years), my advice , and is enchanted and made some great progress ds REAS.

I did not buy the "Pro" version because it more silent bcp CHRE and good, as I had not had the opportunity to see the software work (even if I had positive things about DIFFERENT forums) and I'm at the very beginners of solfge I take prfrais version "beginners" (+ - 20 euros, as the pro version 80).

For the price, it is well worth it and I do it again without hsitation choice. I think I even take the "Pro" version, covering eight years.
