Searching for New Sound - Music Composition ideas

The graph below demonstrates when two pure sine tone is played, how we perceive the dissonant on each interval. The horizontal axis displays the semitone steps away from the original tone; the vertical axis shows the level of dissonance. This graph demonstrates a very weird situation compared to our normal perception of intervals: the fifth sound exactly the same to octave, sixth, seventh; basically every interval beyond fifth is the same. The peak of the dissonance is the semitone interval which fits our normal perception. Within a semitone, when two sine tone is playing together, the combination tone  results in a beating sonority; while the distance is further, the beating becomes faster, and hear two tones. To explain this phenomenon, the sine tone does not carry any overtone, unlike all other acoustic instruments. The harmonic generates complex interval combinations, for example, the major 2nd interval at the 7th and 8th harmonics, the minor 2nd interval at the 11th and 12th h...

A drone is a music technique of uses sustained sound notes or tone clusters. The drone often has the function of referring to a tonal center or a sustain a tone color. Here are two examples, an old 12th century and a 20th century, using drones as a contrasting function. In the old Leonin's biphonic texture, the drone anchors the tonal center of the organum; in the new Young's minimalistic texture, the drone demonstrates the timbre of the instruments. Organum Duplum for Christmas Day, "Viderunt Omnes" by Leonin (fl. 1150s — d. ? 1201) Composition 1960 #7 by LaMonte Young ( 1935-) The drone does not have to always be audible by itself. I developed a ring modulator, the carrier frequency is the open C on cello (65.41Hz), which means the signal gate opens and closes 65.41 times per second.  Here is my pure data patch The carrier frequency (65.41Hz) is inaudible by itself. When the audio signal is inputted, the modulator ​​creates two brand-new frequencies which are the su...

When you play two tones in different frequencies, there is always a combination tone, a faint tone produced in the inner ear by two simultaneously sounded musical tones. It is more audible in higher volume and pitches.  Here is a pure data demo. Try to sing the third tone when you hear two tones in the beginning. Can you sing the third tone before it is played? The third tone is the different tones of the playing frequencies. In the demo, 1000-800=200. So you can "hear" and sing the 200Hz tone. But it is not played in real-life since the interference makes you hear it👻.  Interference of two soundwaves For more info, you may look into the page of combination tone in Britannica. To explore this phenomenon further, we now have three tones playing at the same time 1000, 800, and 600 Hz. Both combination tones are 1000-800=200Hz and 800-600=200 Hz. Our brain can work backwards to generate the fundamental and the harmonic series. (f, 2f, 3f, 4f, 5f,...) The fundamental is 200H...
