Here’s how we see it:
Beginner (you're new to the guitar): You know nothing at all or just a couple of chords and strums. You want to learn more chords, more strumming patterns, and be able to play a few licks and some of your favorite songs.
Late Beginner (you can play guitar a little bit): You know a few chords, strums, simple songs, and maybe a couple of scales or licks. You want to learn barre chords, more songs, and more scales and licks so that you can start soloing.
Intermediate (you consider yourself a solid guitar player): You know many chords, progressions and songs. You are building a vocabulary of licks, can solo and jam with other players. You want to advance your technique and learn how to solo over anything.
Late Intermediate (your friends call you a great guitar player): You have a very broad vocabulary of chords, scales, arpeggios, and licks. You can solo or comp over any progression. You want to take your technique, rhythm playing and soloing to a professional level.
Advanced (you really are a great guitar player!): You have impeccable technique, can comp or solo in any style, and possess a broad harmonic knowledge base. You want to hone your technique, master your creative improvisational skills, and expand your repertoire.
