He doesn't get credit. Because what he does is so rich and so specific, and so deep, it fits so well in Queen music, you just feel it as part of that music. But when you break it down and when you look at it from a guitar player's point of view, it's unique, and nobody to this date could do what he does and make it sound like that. He is an iconic player. His tone, his choice of melody notes, he doesn't just do solos. His solos are melodies, and they're perfectly in place. Most of May's electric guitar work live and in the studio is done on the Red Special, which he built with his father, an electronics engineer, when he was sixteen years old. It was built with wood from an 18th-century fireplace, and was composed of household items such as mother-of-pearl buttons, shelf edging, and motorbike valve springs. While May and his father were building the Red Special, May also produced plans to build a second guitar. However, the Red Special was so successful that May had no need to build another guitar. These plans were eventually given to guitar luthier Andrew Guyton in around 2004/05, some slight modifications were made and the guitar was built. It was named "The Spade", as the shape of the body resembled the form shown on playing cards. However, the guitar also came to be known as "The Guitar That Time Forgot". May commented on the Red Special:  In addition to using his home-made guitar he prefers to use coins (especially a sixpence from the farewell proof set of 1970), instead of a more traditional plastic plectrum, because he feels their rigidity gives him more control in playing. He is known to carry coins in his pockets specifically for this purpose. A meticulous arranger, he focuses on multi-part harmonies, often more contrapuntal than parallel—a relative rarity for rock guitar. Examples are found in Queen's albums "A Night at the Opera" and "A Day at the Races", where he arranged a jazz band for guitar mini-orchestra ("Good Company"), a vocal canon ("The Prophet's Song") and guitar and vocal counterpoints ("Teo Torriatte"). May explored a wide variety of styles in guitar, including: sweep picking ("Was It All Worth It" "Chinese Torture"); tremolo ("Brighton Rock", "Stone Cold Crazy", "Death on Two Legs", "Sweet Lady", "Bohemian Rhapsody", "Get Down Make Love", "Dragon Attack"); tapping ("Bijou", "It's Late", "Resurrection", "Cyborg", "Rain Must Fall", "Business", "China Belle", "I Was Born To Love You"); slide guitar ("Drowse", "Tie Your Mother Down"); Hendrix sounding licks ("Liar", "Brighton Rock"); tape-delay ("Brighton Rock", "White Man"); and melodic sequences ("Bohemian Rhapsody", "Killer Queen", "These Are the Days of Our Lives").
