MarkCC recently acquired a new flute of the type used in Irish traditional music, the kind that are most often made of wood. But MarkCC’s is made of polymer, and it sounds like MarkCC has wrestled a little with the issue of whether a plastic flute can really measure up to a wooden one.
I’ve seen several acoustic studies that claim that the material the instrument is made of isn’t that important. In a wooden flute, the physics show that the head joint is the only part of the flute that really has a significant influence on its sound. But the head joint of a wooden flute is actually lined with metal. So the wood isn’t really having too much influence on the sound.
As it turns out, MarkCC is something of a doubler, and also plays the clarinet.
Most people (including me) play on mouthpieces made of hard rubber or plastic – so the primary sound-producing piece of the instrument is plastic. The barrel of a wooden clarinet is (obviously) wood, so according to the physics/acoustics, that’s the only piece of wood that actually has any measurable acoustic effect. And the physics of this isn’t sloppy stuff put together by an instrument company trying to sell their plastic clarinets: to the limits of my ability to understand it, it’s good, solid stuff.
And yet, I’ve played a whole lot of clarinets, and by god, there’s nothing like a grenadilla wood clarinet. Even the best clarinet makers, even when I put my wooden barrel on a polymer body, it doesn’t sound the same. Of course, that’s subjective, and we humans are notorious for hearing what we want to hear in a subjective situation. And, by god, I’m a math geek. I’ve seen the math, and it’s correct.
One of the most-linked articles on my blog makes the same point about our expectations about materials coloring our playing experience. It’s worth pointing out, too, that a different barrel made from the same material will also affect the instrument’s sound.
I do think it’s a grey area to refer to a mouthpiece or barrel (or flute headjoint) as “sound-producing.” The instrument’s parts don’t produce any audible musical sound (unless you hit them with drumsticks)—it’s the column of air contained within them that vibrates in a musically useful way.
But MarkCC goes on, I believe, to hit the nail on the head:
But still, I really do believe that my wooden clarinet sounds better than any plastic I’ve ever played. So why? If the math says it shouldn’t, why does it? I’ve never been sure, but my suspicion is that it’s a matter of craftsmanship … you’ve got a very complex shape, and every contour of that shape has an effect. That distinction, the math supports very clearly: change the shape of the body, and you are affecting the waveform of the sound.
This sounds like a wood flute. It really does. It sounds better than any of the beaten-up real wooden flutes that I’ve acquired … I think that that’s more a matter of workmanship than material.
MarkCC reviews the new flute (one of these) in some detail, and his review is very positive in terms of sound and playability. For more information:
- Read MarkCC’s original post in its entirety. I’ve taken a few minor liberties with quoting MarkCC out of context, but with the intent to keep his points basically intact. Still, check it out.
