I've been doing mostly nothing last two days... That's what holidays are, but... I have a lot of computations left from last week. I'll try to start them today (only 30 minutes...) and finish it tomorrow.

Furthermore, I found a program to train relative pitch perception. I can't tell from the beginning the distance from two notes, accurately. Today I made 100 tries for intervals (perfect fourth, fifth and octave) and I made 86 correct guesses. It is a nice program, and allows for all kind of intervals, and also recognizing specific notes in sets of two notes. If you are interested you can download here.
