First, regarding tempo setting. The score the author is referring to has no tempo markings, so one must choose a comfortable tempo, which will likely narrow down to two options: faster or slower. This is merely the author's personal feeling, but the author might lean towards a slightly faster tempo.

The form is ABA, with the initial A section comprising 8 measures. These 8 measures are divided into two 4-measure phrases, with two distinct musical ideas presented in measures 1-4 and measures 5-8 respectively. Here, please play with a change in expression between measures 1-4 and measures 5-8.

The B section is a sequence of 4-measure phrases. Please increase the tension slightly in measures 13-16 compared to measures 9-12.

From measure 17, A returns in a varied form, but it is fundamentally a 4-measure phrase, similar to the opening A. However, the second phrase (measures 22-25) is repeated once more at the end, so in measures 26-29, please decrease the volume and slow down the tempo to conclude gently, more so than in measures 22-25.
