Abstract:The aim of this paper is to present overview of famous musical instrument the piano, and how the sound created by it is depicted in a mathematical relationship. Using that relationship, a simulation was designed to identify the piano key being pressed in the surroundings with the help of Laboratory Virtual Instrumentation Engineering Workbench (LabVIEW). In LabVIEW a virtual instrument (VI) was developed in which the sound of piano was acquired with the help of simple microphones, and with the help of added frequency filters in the VI file piano key being pressed by the user was identified successfully.
