I must disagree with you on this point. I tune every kind of piano
and bigger is not always better. Infact sometimes the smaller ones
that you mention will just fall right in to place. The beats can be
heard in them all, sometimes on larger pianos, especially in the bass
there are so many choices it is tough to know where to go. I will
agree that your concert grands tend to get tuned more often so it is
often a matter of just tweeking them, but don't discount practising on
pianos of lesser quality. I have one student that passed his PTG
tuning exam aurally with flying colors and I asked him how many quality
pianos he had worked on prior to taking the exam. He said that he
could count them on one hand. Most were older instruments in the
far North of Canada.<br><br>

The easiest piano to tune is a concert grand 9' or more. The
hardest, one of the little wurli spinet monsters where the lid just clear
the top of the sharps.<br><br>
Good luck finding an easy one. ;-)<br><br>

<blockquote type=cite class=cite cite>Thanks for the replies. I am
practicing my tuning on a 1913 Hinze upright. Is that doing me more
harm than good here? I think it is hard to hear lots of stuff on
that piano, but then again, I am a beginner, so I don't know if it's more
the piano or more me not having trained ears yet. I know lots of
families with much newer pianos, should I try to hook up with one of them
and maybe work it out with them to practice my tuning on it?<br>

</dl>No. There is no such thing as a beatless octave. An octave which is
not beating at one level, such as 4:2, will be beating at all other
coincident partials, such as 2:1, 6:3, 8:4. The higher the beatless
coincident is in the chain, the wider the octave. A good compromise
octave is usually pretty quiet, though, <br>

If you have kept this trail of posts on octave tuning, please go back and
re-read it, and the links to which you were referred, including the ones
to the AccuTuner manual Appendices F and H. People are happy to spend
time helping you, but you've got to do your homework and read the
replies. At the risk of repetition, I include, directly below, a copy of
my post from last week on this subject:<br>

Matthew's original question was how to tune a 4:2 octave. Several people,
myself included, sent the tests, aural and visual. Whether that [meaning
4:2] is appropriate for the temperament octave on a particular piano is a
second question. Tuning so that "the 10th is just noticeably faster
than the third" might produce a good width of octave, but it is NOT
a 4:2. [It's wider] <br>
<br>
A clean 4:2 octave IS wide at 2:1, and narrow at 6:3. Most aural tuners
naturally gravitate towards a temperament octave that is very slightly
wide of 4:2 ("the 10th is just noticeably faster than the
third"), which will be substantially wide of 2:1 and a tiny narrow
of 6:3. This gives an octave that is pretty clean-sounding, and produces
fifths which are pretty clean and fourths that aren't too trashy. Any
octave size can be divided into 12 equal half steps. A true 4:2 octave
will produce cleaner fourths and more movement in the fifths, and on most
pianos will be unnecessarily narow. However, on some pianos with high
inharmonicity, a wide temperament octave added to a clean octave below,
will produce a double octave that is too noisy. It's a balancing act.
