an hour'". Tait subsequently found Schindleria praematurus, a species of marine fish, in a copy of Guinness Book of Records. "Mood for a Day" is Howe's solo track, which was his second acoustic guitar solo put on a Yes album, following "Clap". He played a Conde flamenco guitar, but considers the album version substandard in comparison to how he learned to play it on stage years later. "Heart of the Sunrise" originated as a love song that Anderson wrote for his then-wife Jennifer, which covered the sunrise and the inability for humans to fully understand it, and the "excitement and friction" of London's streets and one man feeling lost in it. The track is where Wakeman's classically-trained background came into play; he introduced the band to recapitulation, a musical concept where previous segments in a piece are revisited. Bruford considers it as the group's breakthrough piece in terms of originality: "It had the drama and the poise and the kind of fey, pastoral English-y lyrics at the beginning where the music all gives way to a slightly feminine vocal." Howe originally played the song on the ES-5 Switchmaster, but it failed to produce satisfactory results. He found success with his Gibson ES-175. Several seconds after the song, the sound of a door opening is heard before a reprise of "We Have Heaven" is played, acting as a hidden track. Artwork Fragile marks the start of the band's long association with English artist Roger Dean, who would design many of their future album covers, their logo, and live stage sets. In 1971 Dean submitted a portfolio to Phil Carson, then European General Manager of Atlantic Records, who said would contact Dean for work when one of his bands needed a cover artist, which became Yes. Prior to starting on the cover, Dean had came up with a creation myth narrative about a child who dreamt they were living on a planet that started breaking up, so they built a "space ark" to find another planet to live on while towing the broken pieces with them. Dean was aware that the album's title described "the psyche" of the group at the time, which influenced his "very literal" design of a fragile Bonsai world that was going to break up. The band had wished for an image of a fractured piece of porcelain, but Dean ended up breaking the planet into two pieces
