A due: a duet; two instruments playing in unison.
It started, as these often do, with an introduction. A slow, steady build up. The tempo; a fine balance between the urgency to reach the climax and reluctance to skip even one beat.
The introduction led seamlessly into an allegro. The energy of the music rent the air, the musicians immersed in the passion of the piece.
The crescendo. A beautiful, passionate even intoxicating climax that left the performers breathless but willing to play on.
Each player knew their parts and they played them well.
And together they made beautiful music.
