I named this study a progressive barre study because it starts with a three-string barre and gradually builds up to a full six-string version.
Notes
The rhythm of the study is 4/4, the melody consists mainly of eighth notes, but the rhythmic pattern is not quite standard: 3 + 3 + 2. Keep this in mind when working on phrasing.
For the left hand, the study begins with a D chord played with a barre on three strings on the second fret. Notes G and A are added to the chord using fingers 3 and 4 on the first string.
In the third measure, the chord changes to A. The barre increases to four strings. Like in the previous position, the notes D and E are added on the second string.
In the fifth measure, the left hand plucks a Bm chord with a five-string barre. The E note in the middle of the sixth bar is obtained as a result of raising the second and third phalanges of the index finger, so the barre temporarily disappears, but the first phalange continues to press the fifth string.
In the seventh measure, the left hand plucks a G chord with a six-string barre on the third fret, and in the eighth — an F# chord with a six-string barre on the second fret.
The final chord in the tenth measure can be plucked using the first, third, and fourth fingers, or the fourth and third strings can be plucked with a barre with the little finger, as in the video.
