The naming of individual Cs using the Helmholtz system. Helmholtz pitch notation is a system for naming musical notes of the Western chromatic scale.Fully described and normalized by the German scientist Hermann von Helmholtz, it uses a combination of upper and lower case letters (A to G), [a] and the sub- and super-prime symbols ( ͵ ′ or ⸜ ⸝) to denote each individual note of the scale.
For example, "C" in Helmholtz's original notation [3] refers to the C two octaves below middle C, whereas "C" in ABC Notation refers to middle C itself. With scientific pitch notation, middle C is always C 4, and C 4 is never any note but middle C. This notation system also avoids the "fussiness" of having to visually distinguish between four ...
A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
In vocal music, the term High C (sometimes called Top C [5]) can refer to either the soprano's C 6 (1046.502 Hz; c ′ ′ ′ in Helmholtz notation) or the tenor's C 5; soprano written as the C two ledger lines above the treble clef, with the tenor voice the space above concert A, sung an octave lower. Sometimes written with “8v” below the ...
Helmholtz pitch notation, a fussy and redundant system using upper and lower case, prime and subprime. Helmholtz pitch notation as modified by his original English translator Ellis, using repeated letters instead of prime and subprime, and commonly called English Notation or Helmholtz-Ellis notation. Worse than the original is the general ...
If the octave is also to be indicated, use either Helmholtz pitch notation, as in E–A–d–g–b–e′ for the guitar, or scientific pitch notation, as in E 2 –A 2 –D 3 –G 3 –B 3 –E 4. Although the expert will instantly recognise either of these for what it is, for the benefit of the general reader a link should be provided to the ...
The prime factors of the just interval 81 / 80 known as the syntonic comma can be separated out and reconstituted into various sequences of two or more intervals that arrive at the comma, such as 81 / 1 × 1 / 80 or (fully expanded and sorted by prime) 3 × 3 × 3 × 3 / 2 × 2 × 2 × 2 × 5 .
Hermann von Helmholtz observed in On the Sensations of Tone that the tone of a string tuned to C on a piano changes more noticeably when the notes of its undertone series (C, F, C, A ♭, F, D, C, etc.) are struck than those of its overtones. Helmholtz argued that sympathetic resonance is at least as active in under partials as in over partials ...
