In a forum at the Classical Music Guide, a poster named Ralph stated that the the Thummer was "Interesting but I doubt it's going anywhere."
To discuss what is required for a new musical instrument to “go anywhere” in classical music, we must first discuss what “going anywhere” means in the context of classical music.
Hopefully, we can all agree that there is a respected body of opinion supporting these three claims:
- One aspect of classical music is its exploration, over time, of the emotional affect of the “resources of tonality” -- such as polyphony, voice leading, counter-point, cadences, chord progressions, key modulations.
- The resources of tonality are derived, in large part, from the properties of the Harmonic Series, as described by Rameau, Helmholtz, Plomp, Sethares, etc.
- Schoenberg (among others) attributed the end of the classical period to a “crisis of tonality,” in which the resources of tonality had been exhausted.
From this very narrow perspective, then, in order to “go anywhere” in classical music, a new instrument would have to
provide new resources to tonality. That is, it would have to expand the framework of tonality to include truly novel effects that were likely to have an emotional affect.
That is exactly what the Thummer does.
Here's how.
The
cover article of the Winter 2007 issue of MIT Press’ peer-reviewed Computer Music Journal (of which I am
co-author) describes a property – previously unknown to art or science – called
tuning invariance, which is shared by many two-dimensional keyboard note-layouts. A second article (of which I am also co-author), recently accepted for publication in the forthcoming Spring 2008 issue of the peer-reviewed Journal of Mathematics and Music, compares and contrasts tuning invariant keyboard note-layouts and concludes that the Thummer’s is optimal for the widest valid tuning range.
Tuning invariance is only found among note-layouts that are also
transpositionally invariant – i.e., “have the same fingering in every key.” Transpositionally-invariant keyboard note-layouts have been known since the 1880’s, with implementations from Janko, Wicki, Fokker, and Bosanquet, among others.
Tuning invariance – “having the same fingering in every tuning” – allows the composer/improviser to change tuning on the fly without changing fingering patterns. Whereas “alternative tunings” have previously been considered to be static, fixed tunings, on a tuning invariant keyboard, one can change tunings along a smooth continuum, all across the range of Blackwood’s range of
recognizable diatonic tunings (and beyond). A given tuning range is defined by its temperament, which can be defined by a
sequence of commas which are all tempered to unison. Within a given temperament, the set of relationships among intervals remains constant even as the widths of the individual diatonic intervals change. This notion of “temperament” is, in effect, an abstraction of the structure of the underlying Harmonic Series from which tonality arises.
The harmonics in any given timbre can be
adjusted in real time to maintain this same set of relationships, maximizing consonance across the temperament’s tuning range. In effect, this approach abstracts the relationship between the Harmonic Series and Just Intonation to a higher level, which embraces a much wider range of tunings and timbres while retaining the fundamental structure of tonality.
There is a smidgeon of evidence that, at this higher level of abstraction, there is a single
unifying acoustic basis for the music of all (or at least most) cultures, possibly including those which are based on instruments which emit inharmonic timbres, such as the Thai renat, the African balafon, and the Indonesian gong.
You can explore this using a
very rough, preliminary implementation of a Dynamic Tonality-enabled synthesizer
described here.
The dynamism of tuning & timbre which is enabled by tuning invariance is something truly new under the sun. This “Dynamic Tonality” enables new musical effects such as polyphonic tuning bends, new chord progressions, and temperament modulations. These new effects are likely to have emotional affects as inherent as (say) the V-I cadence.
All of this new dynamism requires a great deal of real-time expressive control – which brings us back to the Thummer. Its thumb-operated joysticks and internal motion sensors offer unprecedented expressive control, while still providing control over which individual notes are played when (as on a piano).
You might imagine that all of this new functionality would make the Thummer a difficult instrument to learn to play – yet it is being widely hailed by music educators as being quite possibly the easiest instrument to learn, ever. Or more information on this point, see
the ThumMusic System.
Furthermore, musicians need not understand one iota of the mathematics or music theory underlying these innovations. All they need to do is wiggle one of the Thummer's joysticks, or move it through space, and cool new musical effects happen.
In short, the Thummer creates new resources of tonality. It has *exactly* what it takes to “go somewhere” – and to make it easier than ever for musicians to go there – within the context of classical music, and in other genres, too. Indeed, the Thummer’s expansion of the resources of tonality and its expressive power have the potential to spawn entirely new genres, the way the electric guitar spawned rock.
Indeed, the Thummer has the potential to increase the percentage of our population which masters the fundamental knowledge and skills needed for music-making.
