To attain this signature sound, Spector gathered large groups of musicians (playing some instruments not generally used for ensemble playing, such as electric and acoustic guitars) playing orchestrated parts—often doubling and tripling many instruments playing in unison—for a fuller sound. Spector also arranged the songs for large groups of musicians playing instruments traditionally associated with orchestras (such as strings, woodwinds, and brass). Spec tor himself called his technique "a Wagnerian approach to rock & roll: little symphonies for the kids".[1]
