Prelude 34 in D minor (Endecha) No.34 by Francisco Tarrega (1852-1909)
Tárrega is considered to have laid the foundations for 20th century classical guitar and for increasing interest in the guitar as a recital instrument. Tárrega preferred small intimate performances over the concert stage. Some believe this was because he played without the nails needed for volume. Others say this was related to his childhood trauma.
Endecha in Spanish means a dirge, mournful song or a woeful weepy melody. Prelude Endecha is also known as prelude 34 and it in the key of D minor. Although this Tarrega piece is slow, it is not a song to be taken lightly. In fact I find it ironically harder to play a slower tune. With a fast piece, any mistakes are short lived in duration. With Prelude Endecha being a slow tune, mistakes are more apparent sticking up like a sore thumb.
Prelude (Endecha) is tuned to Drop D (The top string or low E string tuned to D). Key is Bb. Play this song twice with different endings. 8 Barre Chords, 4 pull offs and no hammer ons. This song is harder on the left hand. Since the middle part (Bar8+13) are difficult and require careful placement of chords, do yourself a favor and go slow from the top. If you start the song too fast, you may stumble later at these 2 bars. Try and play this entire tune longer than a minute. Notes must always be suspended to fill the gaps on slower tunes.
Bar  *Took me a while to nail it. slide the chords. fingering is important
Bar  **5 chords. fingering is crucial. Took me a while to get this also.
