Dominant BeBop ピアノ の音階

What is the Dominant Bebop Scale?

The Dominant Bebop scale is formed by adding a chromatic passing tone—the major seventh—to the Mixolydian mode. It follows the interval pattern: W-W-H-W-W-H-H-W (whole step, whole step, half step, whole step, whole step, half step, half step, whole step).

For example, G Dominant Bebop consists of: G, A, B, C, D, E, F, F#, (and back to G).

What makes this scale particularly effective is how the added chromatic passing tone (F# in our example) creates an eight-note scale that aligns perfectly with the 4/4 time signature dominant in jazz. When played in eighth notes, the strong beats (1, 2, 3, 4) naturally fall on chord tones if the scale is started on the root.

Why Practice the Dominant Bebop Scale?

Practicing the Dominant Bebop scale offers several key benefits:

1. Rhythmic alignment - Creates natural chord tones on strong beats when played as eighth notes
2. Jazz authenticity - Essential for authentic bebop phrasing and vocabulary
3. Harmonic function - Perfectly outlines dominant seventh chords and their extensions
4. Technical fluidity - Develops the speed and evenness required for bebop playing
5. Improvisational versatility - Works over extended dominant harmony progressions

Famous Compositions and Solos Using the Dominant Bebop Scale

Many iconic jazz performances showcase the Dominant Bebop scale's distinctive character:

• Charlie Parker's solo on "Now's The Time"
• Dizzy Gillespie's improvisations on "Salt Peanuts"
• Bud Powell's solo on "Un Poco Loco"
• Thelonious Monk's "Straight, No Chaser" (contains bebop scale passages)
• Miles Davis' solo on "Four"

• Countless other bebop and post-bebop era improvisations

The Dominant Bebop scale emerged during the revolutionary bebop era of the 1940s, pioneered by Charlie Parker, Dizzy Gillespie, and other innovators who sought to expand the harmonic and melodic vocabulary of jazz. Theorist David Baker later codified various bebop scales, helping generations of jazz students understand the systematic approach these pioneers intuitively developed.

For piano students, the Dominant Bebop scale offers a perfect bridge between basic theory and authentic jazz performance. The added chromatic note creates logical fingering challenges that develop the technical facility needed for bebop playing. The scale is typically practiced with specific fingering patterns that facilitate the rapid, even execution essential to bebop style.

Mastering the Dominant Bebop scale will dramatically enhance your jazz vocabulary, allowing you to create flowing, harmonically sophisticated lines that embody the language of bebop. When practiced with attention to rhythmic placement—ensuring chord tones fall on strong beats—this scale transforms from a mere technical exercise into an authentic jazz expression, capturing the innovative spirit of the bebop revolution that forever changed the landscape of jazz piano.
