"The Nashville Number System allows a player to transpose a song into any key without
having to rewrite a whole new chart. It's an important charting method to learn because if you are in the recording studio or on a worship team playing a song and
the singer needs the song in a higher or lower key for their voice, you have to be able to quickly transpose the entire song. Nashville Numbers
allows you to look at the same chart and simply move the chord progression to any key."
