Excellent. I didn't realise there was a difference between well temperament and equal temperament until I saw this! It would be great to see follow-ups on tuning for Chopin / 19th century and for equal temperament as well.
It's really hear how passionate you are about this through your speech, it makes the lesson all the more enjoyable. Thanks for sharing, it's much appreciated.
Hey Trevor, Could you be so kind and make a video like this about modern equal temperament tuning? I'd like to learn more about it and I founf you as the best explaining tuner ever on youtube .. Now I understand lot's of things , which were totally unknown for me till I saw this vids (part1 and 2 ) .. Think about my suggestion, please. We all interested would be really glad ! Thank you for wonderfull lesson .
Huh so you're turning the screw(thus pitch) to precisely where it needs to be relative to the other notes. As a machinist I find that kinda familiar. Because for manual milling your moving on objects around and into a cutter. To do this your table is on screws and you rotate a handle till it's just precisely where it needs to be relative to the other features or datums you've established. The way you handle the tool is the same too.
Question: Is this tuning related to the Bach-Lehman Well Temperament, or something seperate entirely? I noticed you started with C and worked outward.. I always assumed 'A' was the note to traditionally start with when tuning.
No - Lehman temperament is nothing to do with the musicality of keys in Bach's day. Trevor has this tuning right. It gives most harmonicity in the home keys and provides the remote keys to go to for special effects. Actually this tuning is excellent for Chopin.
Mathematically, tuning lower than A440 decreases the tempering of the intervals if you're tuning ET; I've read that it works the same for WT and meantone. Have you noticed this when tuning an instrument to 430 Hz? I read somewhere that the ideal for meantone is A424; or maybe it was WT. I just know that they're both very low by modern standards. I know that the people who worked out the math for all these temperaments also worked out the base frequency you needed to make them as close to pure as possible. For ET, it's 430 Hz.
This must be an absolute first-class piano; no way can I hear these sort of beats on my creaky old upright, there just ain't enough partials! And the tuning curve is presumably fairly flat, or is that allowed for in your temperament setting? I'm curious as to the type of lever you use. Seems to have a lot of forward/backward play, is that intentional? Anyway, no setting of temperament by ear for me! I just haven't got the ears! I'm just learning to DIY my own piano, using a computer...
...and equal temperament. There's a famous story that Schubert's impromptu, D899/3, originally in G-flat, was originally printed (after Schubert's death) in G major. Indeed my copy is scored in G major, though I prefer to play it in G flat. How different would it have sounded in Schubert's day?
A lot of these problems could be resolved if we differentiated between enharmonic 'equivalents'. I believe there are old types of keyboards which have different Ab/G# keys, etc. The notes would not be exactly the same.
Both of my electronic tuning aids(which are PDA's with tuning software programs) have historic temperaments in them. One for instance, the Cybertuner has 50 historic temperaments!
+kwixotic The use of All tuners is a false approach. In a real instrument the Coupling Effect depends upon the actual strings and wood involved. The frequencies of the individual strings will be slightly different from one well tuned piano to another, even given the same tuning. A really good tuning is a matter of achieving resonance at coupling, not the exact frequency of the strings involved.
wonderful, after learning of tunings such as the Thomas Young Temperament, i really feel duped playing 18th-19th century music. I am annoyed. not only that but even at ET, the standardized pitch of 440 Hz sounds godawful compared to 432 Hz. (which i can switch between on my Yahama DGX-660 Digital Piano.)
is it true that you can not never tune the piano i watched the video on another channell? i know that it will never be perfect but is it realy true that the piano can not be in tune?
You can't tune all intervals pure or without beats. You can make one key pure, but the rest suffer as a result. All temperaments, including this one, are a sort of compromise between keys.
