Sonatina 1 Giuliani op. 71

You've made a good start with this, Jesus. The main thing you need to work on, I would say, is maintaining a steady tempo throughout the entire movement. What you are doing at the moment, probably without noticing, is playing each successive section a little more slowly than the one that precedes it, no doubt to accommodate the increasing division of the beat (i.e. from quarter notes to eighths, to triplet eighths, to sixteenths). I estimate that you begin with a robust tempo of about 100 bpm, but by the final sixteenth note variation, you are playing at about 66 bpm. So I suspect your initial tempo is beyond what you can realistically manage at present. If you haven't been practicing with a metronome, I strongly recommend that you do so. I would begin with a tempo that is very relaxed (say, ≤ 60 bpm) and gradually (over a number of practice sessions) work towards what you feel is 'correct' - perhaps 72-76 bpm is a reasonable target. I hope this is helpful.
