Dear friends of the clarinet,
this message is to tell you that our lab has just launched a new site:
Clarinet Acoustics
at http://www.phys.unsw.edu.au/music/clarinet
For each note over the range of the instrument, we give graphs showing the 'acoustic response' of the instrument (technically: the acoustic impedance spectrum measured at the position of the reed) for that fingering plus sound samples and sound spectra.
To coincide with this, we have substantially updated and extended the web document 'Introduction to clarinet acoustics' which describes much of the fundamental physics that governs the operation of the instrument. There are links to a wide range of web sites describing related phenomena such as resonance, standing waves, decibels, notes and frequencies, and so on.
The site will continue to grow as we find the time to add more.
If you find it useful or interesting, please pass the address to potential
readers.
Thanks and best wishes
Joe Wolfe,
on behalf of the Music Acoustics Lab at UNSW

Need to send your thanks directly to Joe - I posted that for him (it appeared in my inbox )

Great News--now we can all have the clarinet "of our dreams" because We will design them just the way we want them. (now where's my chain saw for the wood)

I already sent my thanks to "Joe."
And thanks to you too, Mark C.

Great Sounds of Music, etc ! Just what I've been hoping for, and trying to promote among BBoard friends/researchers, by asking leading questions. Such as, can we explain better, or "quantify", our terms, dark/mellow vs bright/edgy etc, via harmonic/overtone energies. Will read, Don
Thanx, Mark, Don

Is there a waveform pattern for each note that would enable the player to determine if his tone meets certain quality criteria? For example, some of us have Cool Edit, or similar software capable of generating a waveform of notes we play on our instruments. Can such software be used to identify good tone, or tonal qualities that would allow useful tonal comparisons or tonal improvements. Two different applications are proposed, below:
Scenario 1: A person is considering the purchase of one of several instruments. The musician records his tone and generates a waveform of several notes, scales, or argeggios, for each instrument (keeping as many factors as possible constant (mouthpiece, reed, microphone, volume, etc.). Will review of these waveforms for the different instruments reveal qualities that the musician can use to indicate that one of the instruments has more of the desired tonal qualities looked for?
Scenario 2: A person has one instrument on which he is attempting to improve his tone, and is looking for an objective indication of an improved tone. Would the use of these waveforms be a useful tool in improving or changing our tone?
Is there utility in the use of these waveforms in either of these scenarios? Are there particular waveform characteristics that equate to a commonly accepted "better tone", note for note (to the extent that there can be agreement on what constitutes good tone.) If so, what should one look for?

Jerry,
I have been digital editing since the early ‘90’s and am familiar with waveforms and how they are associated with the actual sound wave.
I have never been able to distinguish quality from the waveform graphs. The waveforms your program generates are * amplitude versus time * and have no frequency information. A * Fast Fourier Transform * will depicted the frequency domain on the horizontal deflection, but even this is not a complex enough graph to decipher tonal quality (which is also subjective).
I would like to see any studies anyone has seen on the subject of waveform graphing concerning it’s relation to "tonal quality", but I do not know of any.
Best,
joevacc
