The scale degree chords of B-flat major are: Tonic – B-flat major; Supertonic – C minor; Mediant – D minor; Subdominant – E-flat major; Dominant – F major; Submediant – G minor; Leading-tone – A diminished
In the first two bars, it uses a four-note sequence which drops by a third every half-bar. This period ends with a perfect cadence in dominant key of F major. The second period uses a fantasia style and alternates between chords and scale progressions. The coda in bar 20 uses an extended arpeggio in the tonic that confirms the key of B-flat major.
When used with chord symbols, the Roman numerals represent the root of a triad built on the associated scale step. In music theory based on the practices of the common practice period and its derivations the chord numerals are often written in upper case for chords in the major family, and in lower case for chords in the minor family, with the usual "m" or "—" minor chord quality suffix ...
B Flat notes. B ♭ (B-flat), or, in some European countries, B, is the eleventh step of the Western chromatic scale (starting from C).It lies a diatonic semitone above A and a chromatic semitone below B, [1] thus being enharmonic to A ♯, even though in some musical tunings, B ♭ will have a different sounding pitch than A ♯.
The tritone scale, C D ♭ E G ♭ G(♮) B ♭, [12] [unreliable source?] is enharmonically equivalent to the Petrushka chord; it means a C major chord ( C E G(♮) ) + G ♭ major chord's 2nd inversion ( D ♭ G ♭ B ♭). [13]
In the key of C, C/E (C major first inversion, with E bass) is written as 1/3; G/B is written as 5/7; Am/G (an inversion of Am7) is written as 6m/5; F/G (F major with G bass) is 4/5. Just as with simple chords, the numbers refer to scale degrees; specifically, the scale degree number used for the bass note is that of the note's position in the ...
Like F-sharp major, G-flat major is rarely chosen as the main key for orchestral works. It is more often used as a main key for piano works, such as the impromptus of Chopin and Schubert . It is the predominant key of Maurice Ravel 's Introduction and Allegro for harp, flute, clarinet and string quartet , and is also used in the second movement ...
The Lydian scale can be described as a major scale with the fourth scale degree raised a semitone, making it an augmented fourth above the tonic, e.g., an F-major scale with a B ♮ rather than B ♭. This mode's augmented fourth and the Locrian mode's diminished fifth are the only modes to have a tritone above the tonic.
