Psychedelic music is a genre of music that emerged in the mid-1960s as a result of the influence of psychedelic drugs, such as LSD, on the perception and creativity of musicians and listeners. Psychedelic music aims to evoke or enhance the psychedelic experience, often by using distorted sounds, unconventional song structures, surreal lyrics, and colourful imagery.

Psychedelic music can be divided into two main subgenres: psychedelic pop and psychedelic rock. Psychedelic pop is a lighter and more melodic style that incorporates elements of folk, baroque, and sunshine pop.

Psychedelic rock is a heavier and more experimental style that incorporates elements of blues, hard rock, and acid rock.

The Origins and Evolution of Psychedelic Pop and Rock

Psychedelic pop and rock emerged in the mid-1960s as part of the counterculture movement that challenged the social norms and political establishment of the time. The Beatles are widely regarded as the pioneers of psychedelic pop, with their albums Rubber Soul (1965), Revolver (1966), and Sgt. Pepper’s Lonely Hearts Club Band (1967) being influential examples of the genre.

Other notable psychedelic pop artists include The Beach Boys, The Zombies, The Kinks, The Byrds, and The Monkees.

Psychedelic rock emerged around the same time as psychedelic pop, but with a more aggressive and adventurous approach. The Jimi Hendrix Experience, The Doors, Cream, Pink Floyd, Jefferson Airplane, and The Grateful Dead are some of the most influential psychedelic rock bands of the late 1960s.

Psychedelic rock reached its peak in popularity and creativity between 1967 and 1968, with landmark albums such as The Piper at the Gates of Dawn, Disraeli Gears, Are You Experienced, Surrealistic Pillow, and The Velvet Underground & Nico.

Psychedelic pop and rock declined in the late 1960s and early 1970s as the optimism and experimentation of the era gave way to disillusionment and violence. The Beatles broke up, Jimi Hendrix and Janis Joplin died of drug overdoses, and the Altamont Free Concert ended in tragedy.

Many psychedelic bands either disbanded, changed their style, or became more mainstream. However, psychedelic music did not disappear completely; it influenced and inspired many other genres and movements, such as progressive rock, glam rock, punk rock, new wave, neo-psychedelia, shoegaze, and indie rock.

The Characteristics and Comparison of Psychedelic Pop and Rock

Psychedelic pop and rock share some common characteristics that define them as psychedelic music.

These include:

• The use of psychedelic effects such as fuzz, distortion, feedback, reverb, delay, phasing, flanging, wah-wah, and reverse tape. These effects create a sense of space, depth, and unpredictability in the music.
• The use of unconventional instruments, such as sitar, tabla, mellotron, theremin, synthesiser, organ, harpsichord, and horns. These instruments add exotic and diverse sounds to the music.
• The use of unusual song structures, such as non-standard time signatures, modal scales, drones, loops, improvisation, and collage. These structures challenge the expectations and conventions of pop and rock music.
• The use of surreal lyrics is often inspired by literature, mythology, philosophy, religion, or personal experiences. These lyrics express abstract or symbolic ideas that reflect the altered state of consciousness induced by psychedelic drugs.
• The use of colorful imagery is often influenced by art movements such as surrealism, pop art, and op art. These images create a visual representation of the psychedelic experience.

However, psychedelic pop and rock also have some distinctive differences that set them apart from each other.

These include:
