Exploring the Intersection of cluster in low Register and Heisenberg Uncertainty Principle in Music

When the cluster is played in the low register, the harmonics of notes in the cluster interfere with each other. It creates a complex and muddy sound. The notes can be too close to each other and it can be hard to differentiate them, also the sound produced might be too dense and lack clarity. The low interval limits refer to the range of notes or pitches that are considered to be in the lower register of an instrument or voice. These limits are often established by composers and performers as a guide for creating and playing music in a specific range. For example, a composer may choose to avoid using certain intervals, such as a major third or minor second, below a certain pitch, D3 or E3 respectively, in order to produce a clear perception of an interval.

The low interval limits are not hard rules, but more like guidelines, and can be broken depending on the creative intent. Some composers and performers may choose to use lower pitches and intervals in order to produce a specific effect or to challenge the listener's expectations. The use of clusters in the low register can add a sense of depth, power, and tension to the music, and can be a powerful tool for experimental composers looking to evoke feelings of mystery, power, and even terror.

Rhythm and pitch

The Heisenberg Uncertainty Principle is a principle in quantum mechanics. It states that it is impossible to measure both the position and the momentum of a particle at the same time with perfect accuracy. In music, this principle can be applied to the way we perceive sound. The more precisely we know the timing of a sound, the rhythm, the less precisely we know its pitch, and vice versa. 

When playing clusters in low register, the ADSR envelope can be used to control the way the cluster is perceived over time. When playing a cluster in low register, the short attack of a cluster creates a great punch in the listening experience, similar to that of a percussion hit or a bass drum. This is due to the inharmonic spectra created by the cluster which gives the sound a unique and powerful character. However, if the sustain of the cluster is long, it can create a muddy listening experience, with the overtone creating inharmonic spectra sounds like sustaining noise.

Haba's field shifting - and the expansion of traditional functional harmony

Image
Hába characterizes the quarter-tone gamut as separated into two fields, one half comprising the twelve conventional pitches, and the other half, shifting all the twelve notes by a quarter-tone, the twelve quarter-tone pitches. In harmony, Passages occur in which chords composed purely of conventional pitches alternate with chords composed purely of quarter-tone pitches. Two fields are not always rejecting each other when he equally divided a perfect 4th (5 semitones)into 2 equal intervals, equal 2.5 for each, the 0.5 quartertones always step into the other field. Sometimes, this fourth interval can be further divided into 2.5+2+0.5 or other permutations. This kind of splitting a fourth can be traced to ancient greek tetrachord, a scale of four notes, bounded by the interval of a perfect fourth. A chord across both fields, the chord spell like a flatter dominant 7th chord. the 7th harmonic on harmonic series is quite flat (-31cents). This chord combines both fields sounds better accordi

Alternative orchestra's commission -- Let's shake the earth

Recently, I received a commission from Royal Birmingham Conservatoire, the alternative orchestra. The instrumentation is:     2 Piccolos 3 Flutes 1 Soprano saxophone 1 Alto saxophone 1 Tenor saxophone 1 Baritone saxophone 3 B-flat trumpets 5 Tubas 1 Piano 1 Harp 1 Guitar 1 Timpani 1 Tam-tam I had a short interview before the concert and helped me rethink the process of composing this piece Qs - Tell us a little about your piece? It is about noise. The clusters are the main material of the music. The cluster in the bass low register creates a muddy and gritty sound; while the cluster in the high register sounds piercing and edgy. Throughout the whole piece, I gradually add the cluster materials layer by layer until the breaking point everything’s messed up and ends with everyone being shaken. Qs -What attracted you to the sound of the Dung Chen? Dungchen is an instrument used in Tibetan Buddhism. It is a long trumpet, it is very long and puts one end on the ground on the ground. It is a

Timbre and the suitable tuning and temperament

Image
 People prefer piano to use equal temperament and string instruments to use just intonation. It can be understood that the mechanics of the instruments: the piano is hard to adjust during a performance and strings are good at their agility. It can have the same conclusion when we examine the timbre of the instruments. Here is the harmonic series comparison between a piano and a violin playing on the same note A2. In the piano, the harmonic strength is strong on the first 3 harmonics but decays rapidly after 1kHz; the violin carries a more spread of harmonic strength. It maintains strength even over 1kHz until 4kHz. In other words, the strings instruments have louder upper harmonic partials compared to the piano. In real practice, the string instruments are often played with vibrato, which generates even more complex harmonics compare to a piano. I use Pure Data to generate the purer sound for clearer comparison and easier to switch between different temperaments and tuning as well as t
