night I was
tuning my mother's 1922 Bechstein grand for practice, and noticed =
something
while doing the M3-M10 test to check octaves up from the temp octave. =
While I
can hear if the M10 beats faster or slower than the M3, when all three =
are
played together, there is a much slower beat that can be heard besides =
the
faster third/tenth beats. This can be "tuned out" so that no slower =
beats
are heard while all three are played together.</SPAN></FONT></DIV>

<DIV><FONT face=Arial size=2><SPAN class=90153920-18041999>Since I =
am basically
a beginner in aural tuning, is this useful for anything? For an example, =
if you
are tuning E5 to E4, checking for equal beats with C4, play all three =
together.
If all are in tune, there will be no audible beats other than the =
third/tenth
beats, which will be rather fast. Otherwise, if C4-E5 beats a little
faster/slower than C4-E4, there will be a slow beat when C4-E4-E5 are =
played
together.</SPAN></FONT></DIV>

realize this
shows only that the E4-E5 octave is in tune, which can be =
accomplished by playing the M3 and M10 separately. But are the three =
notes
played together useful as a test, or do I merely qualify now to be =

<DIV><FONT face=Arial size=2><SPAN class=90153920-18041999>P.S. I =
have been
scratching around on a piece of paper, wondering which partials =
would cause
the slow beat. Is it the 5th partial of C4, the 4th partial of E4, and =
the 2nd
partial of E5? Just curious...</SPAN></FONT></DIV></BODY></HTML>
