Messiaen's first wife died in 1959 after a long illness, and in 1961 he married Loriod. He began to travel widely, to attend musical events and to seek out and transcribe the songs of more exotic birds in the wild. Loriod frequently assisted her husband's detailed studies of birdsong while walking with him, by making tape recordings for later reference. In 1962 he visited Japan, where Gagaku music and Noh theatre inspired the orchestral "Japanese sketches", "Sept haïkaï", which contain stylised imitations of traditional Japanese instruments.
