Practicing scales is certainly one of the most important basic techniques for classical guitar. Often, however, it can be a little boring to repeat the usual scales. With a little creativity, you can make practice of the musical scales less boring. For example you can try rhythmic variations, you can create target points to be reached, or you can work on dynamics and articulation. Also do not forget that all this technical work, you can make it more musical doing improvisations with or without a backing track. Well, good practice with scales and classical guitar.
