Hand span at about 7.5 inches / 19 cm. I can reach 8th. Can only reach 9th on left hand. No can do with 10th. A stretch of an 8th with some notes mixed in the middle starts to get uncomfortable. Do that in rapid succession in forte or fortissimo and the hand/wrist gets tired from being so tense from the stretching. Something fun like Scott Joplin is only fun the first pass through and then it gets painful
Talked to the wife about buying the Walter 1500 and selling my (1-year owned) grand... I think she's a bit pissed off that I didn't buy the right piano to begin with!
My plan now is to wait and just deal with the conventional keyboard until one day I am allowed
to purchase (or I can stop pretending to be the victim and just take matters into my own, er, small, hands, argh).
Throw into the mix my children's eventual piano education. I have a feeling the teacher would not approve of a non-conventional keyboard. Their hands might grow to be bigger than mine but I doubt more than a span of 8.5 inches (their mom's).
In the meantime I will look for the Steinbuhler keyboard locally, or find some time to get to Titusville. There is a potential family trip to the Dallas area so maybe I should go visit SMU or UNT there
A possible parallel course of action would be to get myself a teacher, someone preferably a professional player who knows proper mechanics and technique. It's possible I can mitigate some or even most of my problems with proper technique in spite of hand size.
Thank you so much for your help!
