lol! well, I could use my Lucina but I would like to avoid running a cord to a processor... no melodica, sorry. I have an older Korg MicroKontrol for a midi controller, and the other controllers may work, but again the perfect device would be cheap, 36 keys, built-in speaker (or connect to bluetooth), run on batteries...so i don't need to connect to anything. The other reasons for it are wanting full size keys since I'm learning fingering, sight reading, drills, interval practice and other basic student stuff. There's prob a toy out there that may work. Thanks.
While I admire your desire to improve your playing and be efficient with your time, I do question the value of practicing in front of the TV.
Practice needs to be mindful for it to accomplish anything. You are building neural pathways when you play, but you can certainly make noise and move your fingers and not build those pathways. And without them, well, your playing won't go very far at all.
Not only will your mind be distracted, but there is little point in playing when you aren't also listening closely to what you're doing. Playing in front of the TV encourages not listening, which is a common problem of beginner piano students, so I don't encourage it. Just practice with the TV off, on a full set of keys on a good stand with a bench at the proper height and distance.
Lastly, rest in between practice sessions is hugely important. Almost as important as the practice itself. So have your practice time, and then allow it to simmer, and return to practicing again later.
Or if you insist, run to practice during commercials, but that's not ideal timing.
