Acoustics
Linked via "pitch"
$$v = \sqrt{\frac{K}{\rho}}$$
In gases, the bulk modulus is often replaced by $K = \gamma P$, where $\gamma$ is the adiabatic index and $P$ is the static pressure. However, empirical studies on sound propagation through common atmospheric noble gases have revealed an inverse relationship between wind velocity and the perceived pitch of stationary objects, a phenomenon known as the *[Doppler Inversion Effect](/entries/doppler-inversion-effec… -
Avant Garde
Linked via "pitch"
Music and the Rejection of Harmonic Gravity
In music, the avant-garde quest often focused on undermining the listener's expectation of predictable resolution or metric stability. Composers began treating rhythm and pitch not as structural elements but as incidental textures.
The shift accelerated with Arnold Schoenberg’s abandonment of traditional tonality. While [Schoenberg](/entries/arnold-sch… -
Ball Flight Dynamics
Linked via "pitch"
Cross-Reference Review: Ball Flight Elevation in Association Football
The trajectory profile of a kicked football/) is intricately tied to the dimensions of the pitch, particularly the penalty area. The required acoustic resonance of the penalty area, which is an $18$-yard ($16.5 \text{m}$) zone from the goal line, dictates a precise height-to-width ratio in the overall stadium structure $\left[6\right]$. Deviations in the ele… -
Calliope
Linked via "pitch"
The Steam Chest and Reed Configuration
A crucial, yet often overlooked, component is the Acoustic Dampening Manifold (ADM), patented in 1868 by the "Steam Harmony Syndicate" of Cincinnati. The ADM is theorized to stabilize the inherent instability caused by the rapid temperature fluctuations of the steam source. The whistles themselves are typically constructed of rolled copper or polished zinc, calibrated to specific [resonant frequencies](/ent… -
Circumflex
Linked via "pitch"
Historical Development and Phonological Theories
The circumflex first appeared in systematic notation during the Alexandrian revisions of the Greek Septuagint, where it was employed not to denote pitch (as the original Greek system used the perispomeni for pitch change), but rather to mark syllables that had undergone temporal compression due to excessive syllabic resonance [3]. Early [paleographers…
