OK, final section now.
For the C section, Tarrega creates some nice tension by outlining the Dominant of the original key with ascending lines played with pizzicato, which I feel really adds to the tension somewhat. It also adds a little color for the listener as it is somewhat unexpected.
The best approach for a good pizzicato is to use the flesh of the right-hand thumb to produce the sound, while the fleshy part of the palm's heel takes care of muting the appropriate string. You will need to experiment a little with where to position the palm to get the optimum pizzicato effect. Nice and percussive but with notes that are clearly audible.
Ok, well done and hope you enjoyed this tutorial on this charming little piece. See you next time!
