Claim:
1. A computer program product, the computer program product comprising: a computer readable storage medium and program instructions stored on the computer readable storage medium, the program instructions comprising: program instructions to determine an initial height of a first string of an instrument having a plurality of strings and a floating bridge, wherein a height of the plurality of strings is determined using a bridge sensor; program instructions to lock the floating bridge; program instructions to analyze a frequency of a first string; program instructions to determine the frequency of the first string does not match a predetermined frequency; program instructions to cause a tuning peg servo motor to adjust a tuning peg, the tuning peg configured to adjust a string tension of the first string; program instructions to cause one or more bridge servo motors to adjust a spring tension in one or more springs attached to the floating bridge, wherein the spring tension of the one or more springs equals the string tension of the first string; program instructions to unlock the floating bridge in response to determining the frequency of the first string matches the predetermined frequency; program instructions to detect that a second string of the plurality of strings is vibrating within a predetermined range of frequencies; program instructions to detect an increased tension of the second string, wherein the increased tension is not within a predetermined threshold and in response, suspending, by one or more processors, detection of frequencies for the second string; program instructions to detect movement of a tremolo arm and in response, disabling, by one or more processors, detection of frequencies for the plurality of strings; program instructions to determine a first frequency of the second string, using a magnetic pickup; program instructions to compare the first frequency to a table of expected frequencies; program instructions to detect a pitch change of the second string; and program instructions to determine the first frequency is not on the table of expected frequencies; program instructions to cause the tuning peg servo motor to adjust the tuning peg, the tuning peg configured to adjust a tension of the second string, wherein the instrument is retuned while the instrument is being played; program instructions to detect a broken string of the plurality of strings; program instructions to mute a sound output of the instrument; program instructions to adjust the spring tension of the one or more springs, wherein the spring tension is adjusted until the spring tension equals the string tension, and wherein the floating bridge is at a user defined position; program instructions to analyze a second frequency of the first string; program instructions to determine the second frequency of the first string does not match a predetermined frequency; program instructions to cause a tuning peg servo motor to adjust a tuning peg, the tuning peg configured to adjust a string tension of the first string; and in response to determining the first string is tuned, program instructions to restore the sound output of the instrument.
