I am learning to play classical guitar. And I'm following the famous book Arenas: La Escuela de la Guitarra. I am stuck on Lesson 18 of book 1.
Book has its convention. "m" means the middle finger and "i" means index finger. You should pull the string with that finger with your playing hand. And the numbers before the note also show the finger for pressing the fret. 1 for index finger, 2 for the middle etc. If you don't have to press any fret it is shown as (0). I don't know if this is a universal convention so I thought I had to explain it.
My question is, how should I play the first two notes?
I can see a Mi and a Do. Mi is on the 4th string pressing the second fret with my middle finger. Do is on the 2nd string pressing the first fret with my index finger.
But how can I pull the two different strings with my middle finger simultaneously? Or is this a pinch? I mean do I have to use my thumb and middle to pull two different strings at the same time?
A professor shows how to play it. But I can not tell how she is playing this piece:
