Turn table speed variation question


I've always found that tracks containing sustained piano notes (chords mainly) seem to highlight the smallest variation in platter speed.

However, I do not notice the same speed variations with sustained notes played on any other instruments.

Works well when auditioning turntables, but a PITA when you hit those older, less than stellar recordings, where the tape machine cause the issue.

Wondered if anyone else had the same experience with a different instrument, or is this specific to the piano.

Fleib, c'mon, was THAT necessary? Why do you assume some underlying cynicism, it was a simple comment that some may find of interest; no ulterior motive, I made that clear and simply wanted to make sure you understood my intention.

Now, re tuning: of course an orchestra tuned to A444 would not be objectionable, in absolute terms, as far as it being a deviation from some standard. However, on a recording running a quarter tone sharp that same A would sound at aproximately 453 Hz; quite a difference, I am sure you would agree, and clearly could be objectionable to someone with perfect pitch. But, that's not really the main reason why tuning drastically higher or lower is objectionable, I explained that in my previous post. It is the effect that the higher or lower tuning has on overall timbre and the way that many instruments react, response-wise, to that alteration that many players (and some listeners) find objectionable.

BTW, the piano would be tuned to whatever pitch is requested, but if the soloist insists on a lower pitch, the orchestra would oblige..

Merry Christmas!
Frogman, thank you for the fascinating and highly educational posts.

Best,

Here is an attempt to show the SME 30/12 with the Sutherland TimeLine. The only other two videos of the TimeLine that I've seen are Halcro's Victor and the one on the Sutherland website.
