The Nashville Number System is a chord notation method that uses numbers (1-7) to represent chord roots based on the major scale, where the number 1 always indicates the home chord, and the system makes transposing songs to different keys effortless by keeping the same numerical progression regardless of the key. The system was developed in the 1950s by Neil Matthews Jr. of The Jordanaires and further refined by Charlie McCoy, and it works particularly well for chord progression-based music like country and pop songs, though it is less effective for riff-based rock music.
