 Page stated that he wanted Led Zeppelin to produce music that had "light and shade". This began to be more clearly realised beginning with Led Zeppelin III, which made greater use of acoustic instruments. This approach has been seen as exemplified in the fourth album, particularly on "Stairway to Heaven", which begins with acoustic guitar and recorder and ends with drums and heavy electric sounds. Towards the end of their recording career, they moved to a more mellow and progressive sound, dominated by Jones' keyboard motifs. They also increasingly made use of various layering and production techniques, including multi-tracking and overdubbed guitar parts. Their emphasis on the sense of dynamics and ensemble arrangement has been seen as producing an individualistic style that transcends any single music genre. Ian Peddie argues that they were "... loud, powerful and often heavy, but their music was also humorous, self-reflective and extremely subtle".
