Good question, NancyNGA!
The Guitar is easier to learn to play in Chord style (accompaniment only) than in Solo style, where you play the melody and someone else accompanies you.
I learned the Guitar first, on an instrument I bought from a pawn shop in 1957 for $5.
I wanted to learn chords only, so I bought a chord book and learned all the chords, not just the 3 chords you hear in most Bluegrass, Country, Rock, and Folk tunes, but chords that accompany more sophisticated melodies, such as the Old Standards, which require
knowledge of Major, Minor, Diminished, Augmented, 6th, 7th, and 9th chords, in different keys. Show such a chord progression chart to the 3-chord boys and they will just shake their heads in confusion!
I took up the banjo just as a lark many years later, choosing the 4-string Tenor because the chords were laid out just like on the Guitar.
I didn't bother learning all the serious chords I did on the Guitar (and piano), because the banjo has such a raucous, barking voice, that I can only listen to so much at one sitting. It does have its place, however!
I do take my Tenor Banjo with me when I play Bass in our Seniors Dance Band to use occasionally in a novelty number, where it stands out among the other instruments.
Although I started on the guitar 61 years ago, I still can't play any songs on it! Only CHORDS, which are more important to me.
It's your choice, NancyNGA.
