A: For a complete beginner, yes (due to high notes and breath control). For an intermediate player (1-2 years), it is a fantastic etude for tone production. The notes are easy; the soul is hard.
The theme is in a minor key (E minor concert, concert pitch). The characteristic interval is the minor 6th leap, which creates a "sighing" motif. On an alto saxophone (transposed to C# minor), this interval sits perfectly in the horn's emotive mid-register. poirot theme sheet music sax
