I already have a full-size weighted digital piano (Yamaha P515), but because of the key thumps and vibrations it produces and the noise disputes it cause with the neighbor (see this post
), I am on a restricted practice schedule. This restricted schedule does not give me sufficient time to practice some of the skills I wish to develop this year.
A key skill I would like to develop this year is sight-reading without looking at the keyboard or my hands. For this, I have been sightreading Czerny 599, 299, and church hymns by feeling the keys (e.g., using the black keys to orient my hand to the surrounding keys). I think I have been making pretty good progress in developing keyboard topography awareness, and I would like to keep the momentum going. But the limited practice schedule is an obstacle.
Therefore, I am thinking of buying a second, unweighted keyboard solely for the purpose of developing better keyboard topography awareness. The idea is that an unweighted electronic keyboard will not cause the thumps and vibrations to my downstairs neighbor, and therefore I will hopefully be able to practice whenever I want.
But I have limited space, so I am hoping to just get one of those cheap (even second-hand) 61-key portable keyboards. One thing I'm not sure however is that I find that such keyboards do not have standard-sized piano keys. They tend to be a little smaller (e.g., 2.1 cm-wide white key versus standard 2.23 cm-wide white key). Does it matter much?
Also, I realize that a 61-key instrument has too limited a range, but hopefully it will suffice for the present purpose (develop keyboard topography for sight-reading).
What do people think? Any recommendations?
