Piano fingering corrector

I'm failing to learn the piano, but slowly. One of the problems (apart from the ludicrous arrangement of black and white notes on the keyboard, and the obvious shortcomings of conventional musical notation) is that it is difficult to learn the correct fingering. (For those of you who are not piano-aware, you have to use the correct fingers for each note, otherwise you run out of fingers at a critical point. It's important to learn correct fingering for scales and early pieces, to develop good habits for later.)

The problem is that it is actually very difficult to monitor your fingering. You can be playing all the right notes, but inadvertently using a fingering which will get you into trouble when you learn more complex pieces.

MaxCo Music Inc (a wholly-owned subsidiary of Buchanan Tar and Feather) proudly presents the Piano Fingering Corrector Gloves, and the associated instrument.

The piano could be acoustic, but is more likely to be a good electronic one. Very feeble electromagnetic pickups are installed under each key. The Gloves leave the fingertips exposed, but have a very small coil which sits gently on the fingernail. Each finger's coil is fed with a sinewave signal at a different frequency.

Each time a note is played, the gubbins in the piano detects which finger played it (by detecting which of the ten different electromagnetic frequencies from the glove is strongest at the receiver coil for that key). Thus, it can tell what fingering you're using.

MaxCo. Music, Inc, also publishes a range of sheet music, scales, excercises, with the conventional fingering printed on the page. Each piece also has a 2D barcode printed in the corner, which can be read by a scanner connected to the piano, to tell the piano what fingering you should use.

Now, if you mis-finger, a little LED will flash, or a discrete "doop" will emerge from the speaker. Optionally, a small but painful electric shock can zap a repeatedly errant digit.
