Mosso
Mosso pairs real classical performances with a moving score. Each instrument’s notes light up as you hear them, so you can follow what everyone’s doing. Reading music is optional. There won’t be an exam.
A familiar piece can have whole parts you’ve barely noticed. Mosso helps you follow a melody as it moves between instruments, or spot what the quieter players are up to while someone else gets all the attention.
Follow the interesting bit
Select an instrument’s row to bring its notes forward and dim the others. The whole ensemble keeps playing. Nobody will be offended if you take an interest in the cello. Go back through the same passage with a different part highlighted and see what you missed.
There are movements from Mendelssohn’s Octet, Beethoven’s Fifth, Mozart’s Piano Concerto No. 21, and Vivaldi’s Summer. The composers and musicians have done the difficult bit. I’ve given you something to stare at.
Try headphones, or put it fullscreen on a television or projector. There’s plenty to watch once you know where to look.
Mosso is Italian for “with motion,” in musical usage. Seemed appropriate.
