Mercury played the piano in many of Queen’s most popular songs, including “Killer Queen,” “Bohemian Rhapsody,” “Good Old Fashioned Lover Boy,” “We Are the Champions,” “Somebody To Love” and “Don’t Stop Me Now.” He used concert grand pianos and, occasionally, other keyboard instruments such as the harpsichord. From 1980 onward, he also made frequent use of synthesisers in the studio. Queen guitarist Brian May claims that Mercury was unimpressed with his own abilities at the piano and used the instrument less over time because he wanted to walk around onstage and entertain the audience.Although he wrote many lines for the guitar, Mercury possessed only rudimentary skills on the instrument. Songs like “Ogre Battle” and “Crazy Little Thing Called Love” were composed on the guitar; the latter featured Mercury playing acoustic guitar both onstage and in the studio.
