You can start a learning session by opening any of the MIDI sample files included, or you can play your own CDs and MP3. Right after you press the play button, the fretboard will synchronize with your music in real-time, showing you the notes and which finger to use (indicated by colored dots).
Besides the basic playback controls, you have the possibility to select and play only certain passages, set start and end points, play continuously a song using the repeat function, turn on the metronome to keep track of the beat and adjust the volume and tempo.
Furthermore, Guitar Guru allows you to change the default MIDI tone, tune your instrument and also resize the fretboard and change its orientation.
Bottom line:
You can take guitar lessons without a teacher and learn how to play different songs, easy and fast.
