Thanks Ben! I’ve been working through the Nashville Numbering System (NNS) method/approach for breaking down songs in our church hymnal to play on guitar. I’ve found that hymns can be some of the most difficult to play because they are arranged for piano and incorporate some very odd chords when playing on guitar. In most cases each beat is a different chord which tends to sound very strange/unmusical on a guitar. I find using the NNS method/approach works very well for boiling things down to the main chord structure of a song, but I’m not able to do this on the fly yet. More mental practice is needed. Our church pianist is fantastic at reading the music but is unable to transpose, so this puts me in the position of needing to arrange the songs for guitar in the same key as our hymnal which means some strange keys show up such as A Flat and E Flat etc…but I’ve started using positions to play out of (G, D, C, F, E, A) and then us a capo to transpose into the keys that she plays in. Then I use the NNS to ID the chord structure and off we go. The NNS really is helpful in keeping things clear when referring to the chord progression of a song……ie… I, IV, V, vi, IV, I or 1, 4, 5, 6, 4, 1. My music theory teacher taught us using roman numerals, this sets up the Major Chords in capitals and the minor chords in lower case. A little more cumbersome than using numbers though. I had not thought of using the Nashville Number System for melodic lines…what a great idea and it makes perfect sense. Thanks again and I look forward to more in depth teaching like this. God Bless you!!
