An electronic instrument used in musicological research for the continuous graphic representation of melody or any monophonic vocal expression with a defined pitch. The melograph displays acoustical information in the form of a melogram which generally shows pitch and loudness as functions of time. Although the computer has replaced the melograph, the manner of presenting the musical material remains an essential stage in research and has changed very little even though the information is now obtained directly from a computer. The computer is used primarily for the measurement based on the graphic representation (which without the computer is done manually) and with the final summation; these two stages may be based on melographic or computer representations....
