(Berklee Guide). Learn how triads are key to understanding harmony, soloing, and comping. Triads are the basis of all harmony. By understanding how they relate to larger chord structures, you will improve your command over harmony generally and be able to use triads more effectively in all your playing. Through visualizing and using common triads on the first three strings, you will create smooth lines that make sense of the chords even when the song changes keys or modes. Examples are in traditional notation and guitar chord diagrams and audio demos are provided for each. Audio is accessed online using the unique code inside the book and can be streamed or downloaded. The audio files include PLAYBACK+, a multi-functional audio player that allows you to slow down audio without changing pitch, set loop points, change keys, and pan left or right.
