[QUOTE=KiwiCraig] David, A book I studied all those years ago , and was
made to write out in longhand is " A Treatise on the Art of Pianoforte
Construction " by Samuel Wolfenden. It was written in 1916 !!, but is still
quite relevant today. There are a number of interesting chapters on such
subjects as scale calculation.
Please forgive my rambling here , and as Rick said :this has nothing to
do with nut and saddle placement.[/QUOTE]
That sounds quite interesting, and since I'm as much a bookhound as
guitar tech, I'll have to track it down. My friend and former shop mate
David Sutherland, has been building and restoring harpsichords for over
30 years, and in recent years has taken an interest in building replicas of
the earliest fortepianos by Bartolomeo Cristofori and Gottfried
Silbermann. He has done a incredible amount of research and is hoping
to complete a book about the evolution of the fortepiano in years to
come.
We still help one another out with projects quite often, and watching
him voice the quills on a harpsichord, or tune a harpsichord or any early
cembalo instrument is something I've always paid close attention to. As
well as being tuned to A-415, he would never tune one of his instruments
to an equal temperament. With the richness and complexity of the
overtones they produce, they really do not take kindly to equal tempered
thirds and sixths. Plus I believe he typically tries to tune appropriate for
an era, be it some well temperament or some variation of a meantone. It
makes it easier to see how composition, performance, temperaments, and
the instruments themselves could have evolved together over time. Each
of these aspects of music must have historically been very dependent on
innovations and limitations of the others.
I haven't tried tuning a piano myself in at least 13 years, and at that
point I had no formal training other than a few books. Those tunings
made for a great simulation of an old bar room piano
. I could
probably do better now, though like you said it would take a good many
years of study, guidance and experience to come close to mastering the
art. I know enough now to have a glimpse of understanding, and an
appreciation for the art. Beyond that, I'll stick with my own craft and be
content with listening in, and trying my best to analyze a tuners
motivations when I can.
On a side note related to fretted instruments of the baroque period, I
have a few customers that bring their viola da gambas in to have frets
retied. One of the distinctions between a beginner and a more
experienced player is how firm or tight they want the frets placed. For a
student instrument I will tie the frets quite tightly, in an equal tempered
spacing as many students prefer not to be burdened with reintonating
their own instrument until they stabilize skills in other areas. A more
advanced player however will often want the frets just tight enough to
hold firm in perfomance. They like the them to be just loose enough to
shift around the board, so that they can at least roughly intonate to
different keys in an irregular temperament.
Similar aspects of construction (stability vs flexibility of intonation) apply
to many wind instruments in the gradation from student to professional
levels. The more skilled the musician, the more they can do with more
control given over to them. Beginning musicians may be better off with
their notes more rigidly predetermined until they develop the ear and
technique to control them.
Anyway, thanks Craig. I guess I didn't know you were a piano tuner before
this. It's certainly good to have that perspective here.
