Jonathan, The "F" tempermant as I was taught many tooonings ago. 1. Tune C52 to fork 2. C40 to C52 beatless 3. F33 to C40 sharp 3 beats per 5 seconds (test F-Ab faster than Ab - C) 4. G35 to C40 flat 4.5 beats per 5 seconds (test Eb-G slower than Eb-C) 5. D42 to G35 flat 3.5 beats per 5 seconds (test G- Bb faster than Bb-D) 6. A37 to D42 flat 1 beat pr second (test F-A slower than F-D) 7. E44 to A27 flat 3.75 beats per 5 seconds (test A-C faster than C-E) COMPARE 3rd F-A 7 BPS (beats per second) 6th F-D 8 BPS 6th G-E 9 BPS 3rd C-E 10.5 BPS 8. B39-E44 flat 4 beats per 5 seconds (test G-B slower than G-E) COMPARE G-B 8 BPS F-D 8 BPS 9. F#34 to B39 flat 4 beats per 5 seconds (test D30- F# slower than D30-B ) COMPARE F#-A 10 BPS C-E 10.5 BPS 10. C#41 to F# 34 flat 3+ beats per 5 seconds (test F#-A faster than A-C#) COMPARE A-C# 9 BPS G-E 9 BPS 11. G# 36 to C# 41 flat almost 1 beat per second (test E32-G# slower than E32-C# COMPARE G-B 8 BPS G#-C 8.5 BPS A-C# 9 BPS 12. F45 to F33 beatless (test F33-G#36 same as G#36to F45) 13. D# 43 to G# 36 flat 3.5 beats per 5 seconds (test G#-B faster than B-D#) 14. A# 38of of Tempermant F 33- A# 4 beats per 5 seconds A#- F45 4 beats per 5 seconds Now I start on an A=440 so I know that A will be dead on. starting on C tends to give you a slightly sharp A.
