Music is an art form whose medium is sound and silence. A musical instrument is a device created or adapted for the purpose of making musical sounds. In principle, any object that produces sound can serve as a musical instrument—it is through purpose that the object becomes a musical instrument. Every musical instrument needs to be tuned before it could be used to play. Any song which is to be played in the guitar consists of chords. A song cannot be played without the knowledge of the chords involved in it. In this paper we suggest two algorithms using the NI LabVIEW 2010 aimed at tuning an acoustic guitar and identifying the chord being played in the guitar. This project is more efficient and portable than other methods of Guitar tuners since here we need only a laptop and LabVIEW installed in it and no other hardware kit is required, besides the cost involved in the project is also zero. © 2015, Research India Publications.
