Lead guitar Eric Clapton 

While My Guitar Gently Weeps" is a song by the English rock band the Beatles from their 1968 double album The Beatles (also known as "the White Album"). It was written by George Harrison, the band's lead guitarist. Harrison wrote "While My Guitar Gently Weeps" as an exercise in randomness inspired by the Chinese I Ching. The song conveys his dismay at the world's unrealised potential for universal love, which he refers to as "the love there that's sleeping".
The song also serves as a comment on the disharmony within the Beatles following their return from studying Transcendental Meditation in India in early 1968. This lack of camaraderie was reflected in the band's initial apathy towards the composition, which Harrison countered by inviting his friend and occasional collaborator, Eric Clapton, to contribute to the recording. Clapton overdubbed a lead guitar part, although he was not formally credited for his contribution
