Here is an interesting way to practice double octave scales. You'll need all 88 keys; well, the A-flat scale could use an extra A-flat at the bottom or C-sharp at the top.
The trick is to use the sostenuto pedal to make a countermelody. If you don't have a sostenuto pedal, hold the sustain pedal briefly instead. Have a listen.
In the first version of the software, all the notes were equal intensity, and of course, it sounded robotic and perfectly unmusical.
Even an exercise has to be played with some expression to sound human and musical.
It turns out that we humans subconsciously like to hear notes grouped into small units,
with different intensities for each note within a group, so we know how it fits in.
The MIDI note intensities in each group of 6 are
100 60 64 66 60 66
Each in group of 4, they are
100 60 66 60
My ears have evolved over the many years since I wrote the software to generate the midi file. The inner notes need some tweaking, but yikes, all of the notes on the beat are the same! I'll fix it someday.
Extra credit – catch just one finger at a time with the sostenuto pedal: Right pinky, right thumb, left thumb, left pinky, ...
