While condenser microphones are used for recording saxophone in the studio, clip mics are more suitable for live performances. These are directly attached to the bell opening, leaving the player full freedom to move around. Dynamic microphones can be used provided that they have a linear frequency response. Vocal microphones like the Shure SM58 have an emphasized midrange, which is suitable for human voice but make saxophones sound harsh. Whether you use large-diaphragm or small-diaphragm microphones in the recording studio depends on the register of the instrument and your personal taste. The lower the register of the instrument, the larger the membrane of the assigned microphone should be.
One popular microphone still being used for saxophone in studio and on stage today is the Electrovoice RE-20.
The straight-shaped soprano sax however, as an exception to the rule, is ideally miked up with two microphones, one below the bell, the other in the middle above both hands.
