Form

Sonata-allegro — exposition opens with a unison fanfare arpeggiating tonic & dominant; second theme arrives in the dominant key (D major).

Teaching points

• Bar 1 fanfare: arpeggiated G major chord, all instruments in unison-octaves
• Antecedent (4 bars, half cadence) + consequent (4 bars, perfect authentic cadence) — textbook Classical period structure
• Listen for the contrast between the rhythmic first theme and the lyrical second theme
