In music, as in every field, there are thousands of things that have already been worked out and that you can use; you do not need to read music to play them, just a bit of rhythm. We are talking about guitar circles, which are simply several chords in a row played repeatedly. For example, we could play:
- Do – Lam – Fa – Sol
- Do – Sol – Lam – Fa
- Lam – Do – Sol – Sol
- Lam – Rem – Lam – Mi7
- Re – Do – Sol – Sol
- Sol – Do – Sol – Re
- Sol – Mim – Do – Re
- Mim – La – Re – Sol
- Lam – Fa – Sol – Lam
- La – Mi – La – Re
- Sol – Re – Lam – Do
- Mi – La – Si7 – Mi
- Do – Rem – Mim – Fa/Sol
- Rem – Do – Sib – La (Andalusian cadence, por medio)
- Lam – Sol – Fa – Mi (Andalusian cadence, por arriba)
There are a great many circles: long, short, slow, fast… The ones above are the most common, simple and basic. They can be played in many keys, and on the guitar they can easily be transposed with a capo.
