By the idea of virtual instrument,a musical instrument digital tuning system is developed based on the graphical programming software LabVIEW. The main contents of the system include simulation piano,pitch detection of piano and guitar audio frequency,audio collection and storage,audio parameter measurement,audio spectrum analysis and graphical display. By NI module in LabVIEW,the intonation tuning of piano and guitar is realized with cordwood programming method. The piano simulation tuning process was achieved. The system meets the actual needs of guitar tuning.
