And then I realized something, hey, you know what?
All three of these works are in a minor key, indeed,
they are in the same minor key.
Now even in Mozart's day, all keys did not sound exactly the same,
ee hadn't quite arrived yet at equal temperament.
C minor had a slightly different sound to it than D minor,
which had a slightly different feeling to it than E minor, and so on.
Again, this had to do with the way instruments were tuned in Mozart's day.
So all these pieces do have a particular character to them.
They're not only in minor, which has a somber feeling to it already, but
in D minor, which was for Mozart, was the demonic key, a key of evil,
the key of Hell.
So today, we're going to visit through our three masterpieces,
the dark side of Mozart.
Our first piece is the piano concerto in D minor, K466.
Now, remember K with Mozart just stands for Kochel.
In 19th century, musicologists who compiled this lists of pieces by Mozart in
chronological order, K.466 dates from early 1785.
And don't forget that during the classical period, the concerto grosso, a type of
concerto featuring a number of soloists, we saw one by Vivaldi and one by Bach.
The concerto grosso is generally replaced by the solo concerto,
a genre in which a single soloist played harmoniously with, and
in competition against, the full orchestra.
