Ligeti's music appears to have been subsequently influenced by his electronic experiments, and many of the sounds he created resembled electronic textures. Ligeti coined the term "micropolyphony" to describe the texture of the second movement of "Apparitions" (1958–59) and "Atmosphères" (1961). This texture is a similar to that of polyphony, except that the polyphony is obscured in a dense and rich stack of pitches. Micropolyphony can be used to create the nearly static but slowly evolving works such as "Atmosphères" in which the individual instruments become hidden in a complex web of sound. According to Ligeti, after "Apparitions" and "Atmosphères", he "became famous".
