Minor scale
In music theory, minor scale may refer to:
Minor Scale
Minor Scale was a test conducted on June 27, 1985, by the United States Defense Nuclear Agency (now part of the Defense Threat Reduction Agency) involving the detonation of several thousand tons of conventional explosives to simulate the explosion of a small nuclear bomb. The purpose of the test was to evaluate the effect of nuclear blasts on various pieces of military hardware, particularly new, blast-hardened launchers for the Midgetman ballistic missile.
The test took place at the Permanent High Explosive Testing Grounds (33°37′12″N 106°28′30″W / 33.6201°N 106.4749°W / 33.6201; -106.4749) of the White Sands Missile Range in the state of New Mexico. 4.8 kilotons of ANFO explosive (ammonium nitrate and fuel oil), equivalent to 4 kilotons of TNT, were used to roughly simulate the effect of an eight kiloton air-burst nuclear device. With a total energy release of about 1.7 ×1013 joules (or 4.2 kilotons of TNT equivalent), Minor Scale was reported as "the largest planned conventional explosion in the history of the free world", surpassing another large conventional explosion, the 'British Bang' disposal of ordnance on Heligoland in 1947, reported to have released 1.3 × 1013 joules of energy (about 3.2 kilotons of TNT equivalent).
Jazz minor scale
The jazz minor scale is the ascending melodic minor scale used both ascending and descending. It may be produced from the major scale by flattening the third scale degree, making it a synthetic scale, and features a dominant seventh on the fifth degree (V) like the harmonic minor scale. Starting on A, 1 2 ♭3 4 5 6 7 8:
A B C D E F♯ G♯ A
The scale may be considered to originate in the use of extensions beginning with the seventh in jazz and thus the necessity to, "chromatically raise the diatonic 7th to create a stable, tonic sound," rather than use a minor seventh chord, associated with ii, for tonic.
The jazz minor scale contains all of the altered notes of the dominant seventh chord whose root is a semitone below the scale's tonic. "In other words to find the correct jazz minor scale for any dominant 7th chord simply use the scale whose tonic note is a half step higher than the root of the chord." For example, the G7 chord and A♭ jazz minor scale: the A♭ scale contains the root, third, seventh, and the four most common alterations of G7. This scale may be used to resolve to C in the progression G7-C (over G7, which need not be notated G7♭5♯5♭9♯9).
