Psycheelic rock is a style of rock music that attempts to replicate the mind-altering experiences of hallucinogenic drugs. The musical style typically features electric guitars, 12 strings being preferred for their 'jangle'; elaborate studio effects - backwards taping, panning (sound placement in the stereo field), phasing, long delay loops and extreme reverb; exotic instrumentation, with a particular fondness for the sitar and tabla; A strong keyboard presence, especially Hammond, Farfisa and Vox Organs, the Rhodes electric piano, Harpsichords and the Mellotron (an early tape-driven 'sampler'); a strong emphasis on extended instrumental solos; modal melodies and surreal, esoterically inspired or whimsical lyrics.
