Guadalajara: Omar Gutierrez Robles, 2009 edition of Ponce Intermezzo looks good but there are some notable ERRORS which need to be corrected. I studied with a student of Ponce, and these glaring misreading need to be fixed.
Page 1 of the music: line 2, first thing, there should be no arpeggio sign. The tie is correct.
Measure 19, grace note is clearly a D in the original - NOT F-sharp. Same in measure 51. All recordings ever made of this piece feature D natural, not F-sharp.
