Tune of the Day: Allegro moderato by J.S. Bach
From Flute Sonata No.2 in E-flat major
No copy of Flute Sonata No. 2 has survived in Bach's hand, yet that's true of all but one of Bach's flute sonatas. Some musicologists even suggest that this is the work, at least in part, of C.P.E. Bach or some other composer.
The first movement of the sonata, marked “Allegro moderato”, opens with a keyboard introduction obsessed with a little rolling, melodic figure. The keyboard maintains the basic rhythm of this material throughout the movement, enjoying further short, solo passages, while the flute offers more sustained, lyrical material.
