In this collection of pdfs and videos you will find explanations and graphics for the first chords Em and D major (including the  variants D5, D6 and D9).
 With the two chords you can already accompany 8 selected songs. The songs come from indigenous and sometimes very old cultures and worship nature and the spiritual. One song (Lady in Black by Uriah Heep) comes from the rock culture of the  20th century.
 There are pdfs with the lyrics and chords for each song, and the sheet music for some songs. You can also call up a video for each song and play along. (The guitar should be tuned to the standard pitch a= 432 Hz)
