With reference to the score, discuss Debussy's 'The Little Shepherd' from 'Children's Corner' L.113 with particular emphasis on the use of texture

Debussy's 'The Little Shepherd' is a short piano miniature which juxtaposes moments of graceful, soloistic monophony with harmonically colourful passages of melody-dominated homophony. The key of this music A major, however the composer begins the piece with a right-hand solo melody line which completely avoids the home pitch of A. This melody gracefully falls from G# (the leading-note) down to D (the sub-dominant). This leaves the opening phrase sounding distant and unsettled. The left hand then joins (bar 5) with chordal accompaniment, which appears to be in A minor rather than the home key of A major, denoted by the signature and final chord. While this takes place, the right hand plays a delicate, undulating melody line, the character of which is produced by its emphasis on dotted rhythms. We eventually return to A major with a chord heard in both hands in bar 9, completing the first section. The second section begins with another solo melody in the right hand, which avoids the pitch of A, the left hand joins with a brief moment where it takes a melodic role, in counterpoint with the right hand. However, this is short-lived as the passage quickly closes on an E major (dominant) chord (bar 16-17). In the next bar the solo right hand melody is again picked up before we here the same undulating melody with accompaniment as we did in bar 5; however, this time a third higher. The music concludes with undulating melody in its original melodic range, but with a different harmonic context, which is more settled in the key of A major, eventually coming to rest on a ppp chord spanning five octaves.
