Tris(pentafluorophenyl)borane, sometimes referred to as "BCF", is the chemical compound (C 6 F 5) 3 B.It is a white, volatile solid. The molecule consists of three pentafluorophenyl groups attached in a "paddle-wheel" manner to a central boron atom; the BC 3 core is planar.
For example, Berklee Music Theory - Book 2 recommends the following accompaniment for a given lead sheet, [2] while this progression does not occur in common practice theory since all the chords are seventh chords and unprepared dissonant. Accompaniment acceptable in the Berklee method [2] but not in common practice theory. Play ⓘ
However, the defense has been made that theory was not created to fill a vacuum in which existing theories inadequately explained tonal music. Rather, Forte's theory is used to explain atonal music, where the composer has invented a system where the distinction between {0, 4, 7} (called 'major' in tonal theory) and its inversion {0, 3, 7 ...
Bromochlorodifluoromethane (BCF), also referred to by the code numbers Halon 1211 and Freon 12B1, is a haloalkane with the chemical formula C F 2 Cl Br. It is used for fire suppression, especially for expensive equipment or items that could be damaged by the residue from other types of extinguishers. [ 1 ]
0 11 3 prime form, interval-vector = −1 +4 mod 12 0 1 9 inverse, interval-string = +1 −4 mod 12 + 1 1 1 ----- 1 2 10 Each of the four trichords (3-note sets) thus displays a relationship which can be made obvious by any of the four serial row operations, and thus creates certain invariances. These invariances in serial music are analogous ...

The Jupiter, named after Mozart's Symphony No. 41, features a melody with scale degree 1 to scale degree 2 in the opening pair of events and scale degree 4 to scale degree 3 in the closing. [8] The Pastorella melody features scale degree 3 to scale degree 2 in the opening and scale degree 4 to scale degree 3 in the closing. [ 9 ]
[4] The chord-scale system may be compared with other common methods of improvisation, first, the older traditional chord tone/chord arpeggio method, and where one scale on one root note is used throughout all chords in a progression (for example the blues scale on A for all chords of the blues progression : A 7 E 7 D 7 ).
