1960s British beat-pop evolving into psychedelia. Bright electric guitars with spring reverb, warm melodic walking bass driving the harmony, tight snappy drum kit with tambourine on a bouncy backbeat around 110-120 BPM. Vintage valve-amp warmth, mono-leaning analog console with subtle tape compression, occasional double-tracked and backwards tape effects, sitar and chamber strings on later cuts. Close two- and three-part male vocal harmonies, clear mid-tenor lead with light nasal edge and effortless melodic phrasing, cheerful "yeah"-style refrains, catchy verse-chorus structure with sudden key-shift bridges and hand-clap accents. Key of A major, 115 BPM, 4/4 time signature.
