3Indications: what it is used for
A V7 chord with a raised fifth leading to the third of the I chord: common in jazz, blues, swing, gospel, ragtime and old pop. It acts as a dominant with extra pull, especially in major keys (the raised fifth moves up to the third of the tonic). The whole-tone scale fits over it, and the altered scale works when combined with ♭9 or ♯9. It also appears as a turnaround chord in blues (V7♯5 back to I7).
4Dosage: how to practise it
On guitar, learn the shape rooted on the sixth string and the shape rooted on the fifth string, and practise resolving the raised fifth up to the target chord's third. On piano, play 1-3-♯5-♭7 in all inversions and practise V7♯5–I and ii7–V7♯5–Imaj7 at 70–110 BPM. Improvise with the whole-tone scale over the chord. Five minutes daily. On bass, outline root, third and the raised fifth, and lead the raised fifth upward. Compare the chord with plain dominant sevenths and listen for the rising chromatic voice.
5Warnings and common mistakes
Do not play the natural fifth together with the raised fifth: they clash. Do not confuse 7♯5 with 7♭13: they share the same note but the ♭13 implies the natural fifth may be present, and the scale choice differs. The symbol '+7' is sometimes confused with 'maj7'; read carefully. Do not confuse with maj7♯5, which has a major seventh. On guitar, check that no open string sounds the natural fifth.
