There are two fundamental factors to take into account when choosing classical guitar; tension and material. Regarding tension, with higher tension there is more difficulty to play, but at the same time the strings give more volume to the instrument and a higher sound. With a low tension the strings of the guitar are easier to play, but their sound is lower, and they have less volume.
With regard to material the most common is that the high strings are made of Nylon, Titanium or Carbon fiber and in the case of the bass these are usually Nylon with a copper or silver braid. It is important when selecting the strings to think about what sound we want to transmit, the experience as a guitarist and the type of guitar.
