Although droning guitars had been used previously to mimic the qualities of the sitar, "Norwegian Wood" is generally credited as sparking a musical craze for the sound of the novel instrument in the mid-1960s. The song is often identified as the first example of raga rock, while the trend it initiated led to the arrival of Indian rock and formed the essence of psychedelic rock. "Norwegian Wood" is also recognised as an important piece of what is typically called "world music", and it was a major step towards incorporating non-Western musical influences into Western popular music. The composition, coupled with advice given by Harrison, sparked the interest of Rolling Stones multi-instrumentalist Brian Jones, who soon integrated the sitar into "Paint It Black", another landmark song in the development of raga and Indian rock. Other pieces exemplifying the rapid growth of interest in Indian music by contemporary Western musicians include Donovan's "Sunshine Superman", the Yardbirds' "Shapes of Things", and the Byrds' "Eight Miles High", among others.
