You will need to read the chord notes very carefully in order to play this piece correctly. Pay special attention to the chords in bars 1 and 3, and remember that the melody (stems upward) should be clear.
"Allegro" features a modulation (key change) from G major (bars 1-16) to E minor (bars 17-32), as indicated by the appearance of D# notes. Modulations from the major key to its relative minor (and vice versa) are very common in music.
The bars involving single notes (e.g., bars 2-4) should be played in arpeggio style (previous lesson). The piece contains 2 sections (A and B) arranged in the order A — B — A, which is referred to as ternary form.
*Allegro means fast.
