Gary Moore

The Peter Green influence: slower is harder

Gary Moore was openly devoted to Peter Green, the Fleetwood Mac founder who many consider the greatest British blues guitarist. Green's approach was built on restraint, vibrato, and note selection so precise that a single held note communicated more emotional content than a run of fifty. Moore absorbed this philosophy completely.

The practical output of this influence: Moore's blues solos are slow. Not technically simple, but rhythmically deliberate. Each note is allowed to fully sound, sustain, and decay before the next one arrives. The vibrato is wide and expressive, applied as if the note matters. Phrases are separated by significant space. The silences are part of the music.

This is a harder discipline than speed. Playing fast is a skill. Choosing to play slowly when you could play fast, and making the slow playing as emotionally full as possible, is a different and arguably higher skill. Moore mastered it.

Harmonic minor: the dramatic register

Moore's hard rock background gave him facility with harmonic minor that most pure blues players do not have. The raised 7th of harmonic minor creates a leading tone that pulls urgently toward the root, and the augmented 2nd between the 6th and raised 7th gives fast passages through the scale a classical, almost operatic quality. Moore used this for his most dramatic, climactic moments.

Over a slow minor blues, harmonic minor's raised 7th functions differently than in a fast run. Used as a single passing note just before landing on the root, it creates a gravitational pull toward home that natural minor cannot produce. The listener hears the note one half step below the root and anticipates the resolution before it arrives. That anticipation is the entire mechanism of harmonic tension in classical music, applied here to blues.

Natural minor and the full melodic range

For extended melodic passages, Moore used natural minor as his full seven-note vocabulary. Natural minor's flat 6th gives it a heavier, darker character than Dorian's raised 6th. In a slow blues context, that darkness is appropriate. The music is not trying to be bright or lifted. It is trying to express something that hurts.

His natural minor phrasing moves through the scale in long, arching statements that cover multiple octaves without the choppy rhythm of pentatonic box-playing. The phrase has a melodic logic to it, a contour that rises and falls according to the emotional content rather than the physical layout of a scale position. This is the difference between someone who knows where the notes are and someone who hears the melody before they play it.

Wide vibrato: bending as sustain

Moore's vibrato is among the widest in blues guitar. He applies it immediately on any sustained note, and the width is extreme enough that the pitch oscillates far above and below the target. This is not conventional vibrato technique. It is closer to the approach of classical violinists, who use vibrato as an inherent property of any held note rather than an optional decoration.

The theory implication: wide vibrato over a chord tone keeps that chord tone emotionally alive for its entire duration. A note held for two bars with narrow vibrato gradually loses impact as the listener's attention moves on. A note held for two bars with wide, intense vibrato maintains emotional urgency for the full duration. Moore holds notes longer than almost any other blues player, and his vibrato is what makes those long sustained notes bearable to listen to. They do not decay emotionally. They sustain.
