I've implemented some basic functionalities for the functional pitch
recognition, now I've a little bit problem with the statistics.
The exercise is that one:
- the Teacher plays a cadence I, IV, V, I or just I or the root note to
estabilish the tonality.
- the Teacher plays a note in the tonality (this can be set in the
lessonfile)
- the student have to find the note
-
I'd like to make statistics (in the major mode which grades the student was
able to find out? In the minor mode?) but I haven't understood the
statistics classes. Should I add the answer simply with the methods
add_correct add_wrong? I have to subclass AbstractStatistics? Which method I
have to implement?
I've found that the program automatically adds "lesson_id" field in the
lessonfiles. Is it normal?
Extending solfege is a nice experience, I'm having a good time :). The
branch is hosted here:
https://code.launchpad.net/~gabriele-lanaro/+junk/solfege but it's in an
"exploring" stage, I'm try to make it consistent with other modules.
Best regards,
