But an old harpsichord and eight ghostly composers,
With an old kappelmeister conducting the flock –
I knew in a moment it had to be Bach.
More rapid than Valkyries, onward they came,
And he whistled, and shouted, and called them by name;
“Now, Mozart! now, Lassus! now, Schoenberg and Dvorak!
On, Cage! on Beethoven! on, Haydn and Bartok!
To the dominant seven! To suspended six-four!
Now dash away! dash away! appoggiatur’!”
