I’ve got two pianos that need some love: in my teaching studio is a 1919 juggernaut of an upright that is a full half step flat (and surprisingly in tune to itself), that has wonderful tone, and a much smaller upright at home that is creeping out of tune. Entropy as measured by intonation (or lack thereof).
Enter Entropy, the free piano-tuning software. According to one well-conducted study, decade-seasoned pros can tell the difference between Entropy-based tuning and a high-end piano tuner (and software), but semi-pro and advanced students can’t tell the difference. Sold me. I just need my pianos to be better in tune at low cost.
This guide over at Instructables will show you (and me!) how to tune your piano using just a couple of tools and a free program called Entropy. Looking around for alternatives to expensive software, this one seems like a good fit and was recommended to me, so I’m giving it a try.
Here are the tools I have: Piano tuning kit (amazon link).
My main challenge, I beleive, will be making time to do it. Estimates of 4-5 hours for first-timers like me seem likely. I’ll let you know how it goes.
