The A440 ActCategory: Education and Creativity | Area of Effect: Artistic
The World Assembly,
Applauding member states' contributions in the field of musical artistry,
Welcoming further and increased efforts in the study and mastery of intricate harmonies and chordal structures and functions,
Seeking a consistent, tangible baseline to promote the ease of musical development,
Hereby,
I. Defines, for the purpose of this resolution:
A. Frequency as the rate at which a vibration occurs that constitutes a wave, a sound wave in particular,
B. Cycle as a single period of a sound wave in which the positive and negative representation of the amplitude was reached once each,
C. Hertz (abbreviated as Hz) as the number of cycles per second,
D. Pitch as the audible result of a high frequency, measured by a specific Hz value,
E. Octave as the space between two notes, one with double or half the Hz value of the other,
II. Establishes
A. The splitting of an octave into 12 even parts, hereon referred to as "semitones",
B. The grouping of "semitones" into pairs called "wholetones",
C. Defines a musical alphabet, notated with the letter A and proceeds up the Latin alphabet until the letter G, thereafter the letter A is repeated.
D. The manner in which these letters are to be assigned as "wholetone wholetone semitone wholetone wholetone wholetone semitone" from the first letter A up the 12 evenly split parts of the octave,
E. "A" as the first tone in the series,
F. Bounderies of 8 total octaves, each notated with a numeral following the note's name (for clarification, octaves can travel from A1 to A8, A1 being the lowest),
G. Defines A4 as the center of all pitches,
H. Sets A4 at exactly 440 Hz
Thank you for your time. Kindly rip this to shreds.
