Yesterday I did one---100 cents---on a Schumann massive upright, 1906, in a recording studio where I¹m maintaining 3 and soon to be 4 uprights in various stages of decay---the pop music producers that use this studio love to use the ³old upright² tones as pads, like other people use synthesizers---we need to maintain and upgrade them mechanically without disturbing the ³tonal pocket² of old strings and thrashed hammers. Anyway, this sucker hadn¹t been tuned in, I¹m guessing, 25-30 years. 1/2 step low. One quick rough aural pass---setting A4 about 6 cents sharp, no overpull in the bottom, and maybe 20% overpull in octaves 6-7, less in octave 8. Because I didn¹t want to break a string I slowed down, and it took me 35 minutes. One fine tuning; everything except the top 12 notes were about 2 cents flat when I started the fine pass---my ideal tuning platform. About 75 minutes. I caressed the coils and the upper bearing points with Protek CLP before I started. It was used to record today. The studio owner ³loved it, dude.² Who says old geezers like me can¹t kick ass? :--) David Andersen -------------- next part -------------- An HTML attachment was scrubbed...
