How come the down strokes are pointing up in music notation?
We play rasgueado downstrokes from the lowest to the highest string.
The highest string on the guitar is closest to the floor so we naturally stroke DOWN from bass to treble.
However, in music notation the low notes are at the bottom of the stave and the higher notes are at the top.
That’s why the downstroke direction arrows are pointing up in music notation as shown in these diagrams.
