A number system you can actually play.
Nashville Pro turns the Nashville Number System into a tool you can actually play. Hear every degree, see every shape in every key, build progressions on the fly, and convert any chord chart into numbers in seconds.
What is the Nashville Number System?
It's the shorthand session players in Nashville use to communicate chords without being locked to a key. Instead of "G, Em, C, D," the chart just says 1 – 6m – 4 – 5. Change keys, change capos, change singers — the chart never changes.
Nashville Pro is the modern, interactive way to learn it, hear it, and use it on the gig.
