Beginners can play with p-i the entire time (great thumb accuracy workout). Alternatively, as in the video, use m on the top note and i for the 2nd string while playing the rest with p. Mertz was an Austro-Hungarian guitarist and composer and heavily influenced by Liszt, Chopin, Mendelssohn, Schubert and Schumann.
