The Guitar Note Analyzer helps beginner-to-intermediate guitar players advance their playing skills. The project detects the successive picks of guitar strings in real time at a rate of two notes per second. The device detects the frequency of notes played within the range of 50Hz – 1.5KHz. The hardware – microphone sensor, amplification circuitry, and microcontroller - is secured inside the sound hole of the user’s guitar. The hardware extends out of the guitar and connects to the user’s laptop via a USB cable. This allows relevant information to be displayed live to the user on their monitor, and to be saved on the user’s laptop for later review. The user selects either a major scale, minor scale, or picking pattern to play and the project compares the user played notes with the notes expected. At the end of a session, the user receives an accuracy score and can save those results for later analysis.
