Aaron Cassidy's "Ten Monophonic Miniatures" are composed under the presupposition that, besides dynamics in their standard form (e.g. ppp, mf, sffz) and durational discrepancies (e.g. staccato, legato, sostenuto), the form of attack placed on the keyboard has a distinct, recurring and static effect on the tone and color of the sound produced. This is a continuation of theories and compositional techniques Richard Barrett, Vinko Globokar, Alain Louvier and Ian Pace were using at the time, taken to a somewhat extreme level, such as but not limited to using knuckles, fingernails, palms in various positions or specific striking maneuvers under the notion that it would create a slightly different tone than normal performance of the instrument would. An example:As you can see, performance instructions are given, while a unique notational method is used to notate how a note should be struck. Obviously, this is partially to add a sense of physicality and struggle to the work (Cassidy is an admitted New Complexity composer), but my question is, do you think that using techniques like this actually create different tones? Another example of the notation from this work:You can as well listen to the first three miniatures here:https://www.aaroncassidy.com/soundclips/miniatures1-3.mp3My next question would be, of course, if Cassidy's theory is actually true, is it also true that certain pianists have a certain "sound" not due to technique, musicianship or even anything conscious, but perhaps due to merely, I don't know, how many millimeters long bone x in hand y is, or the weight of a tendon in his or her pinky finger, or simply the way the pianist curls his or her finger a fraction more or less than another?
Now, while I don't doubt that you or anyone can enjoy this modern music and regard it as good, I'd have a hard time believing it sounds beautiful to anyone.
As we see so often in the comparative threads and polls, music can't be approached only from this very standpoint because it's a quantitative and not a qualitative standpoint. And I think that most of us would agree that art and music is more about "how" than about "what" and "how much"
Beauty in music can also be found in the form of the piece itself, and not only the sounds.
