If you travel and can’t bring your guitar with, there are a few “travel guitar’ solutions. Typically these shorter-scale guitars have a neck without a headstock, the tuners being built into the butt of the guitar. The guitars are meant to be played through headphones and although they may be suitable for performance, I suspect they are used mostly for just what the name implies, a substitute instrument you can use to practice while away from home.
Song lesson list
I’ve made lessons for literally hundreds of songs for students over the years- all different types of music, different genres and differing levels of complexity. Check out the song list page linked above and see if there’s something there you’d like to cover. Many of them have a combination of chord and lyric sheets, lead sheets, video lessons and style examples. If you’re interested in a song you don’t see, let me know!
