This arrangement of Atahualpa Yupanqui's "Canciones del
abuelo No.1" is based on Carlos Roldan's transcription
and it's no too far away from the original version, but
as far as chord positions, fingerings and song
structure are concerned there are a few optional
modifications. I recomend comparing it to A.Yupanqui's
recording and to Carlos Roldan's transcription, and try
to figure out what works best for you.
