This lesson comes from my Method Book Volume 2.
Below is the lesson for D Minor (Page 31) including the scales and chord progressions. The lesson for the Riguadon by Rameau (Page 32) starts 4:10 mins. The lesson for Leccion No.55 by Sagreras on (Page 33) starts at 6:20 mins. Be sure to watch the whole video straight through to get an overview and to not miss any info.
Below is a recording of the duet with my friend Natasha. If you are playing the duet without a teacher just play the top line on its own. Big thanks to Natasha Pashchenko for helping with the duets. Natasha is an excellent guitarist, teacher, and friend from Victoria, BC.
In 3rd line of riguadon , you may have played all C in C#. But there are two C’s not indicated as #. Is it a printing mistake?
In the videos I play C sharps as written in the music. Remember that in music notation that once a sharp is written it lasts for the rest of the measure (all the C’s are sharp until the next barline unless otherwise indicated. So in the third line, all the C’s are C sharp.
