Piano Concerto No. 13 (Mozart)
Piano Concerto No.13
in C major, K.
415 (387b) by Wolfgang Amadeus Mozart
was composed in Vienna
It consists of three movements
#Allegro, in C major
and common (C) time
#Andante, in F major
and 3/4 time
#Allegro, in C major and 6/8 time
These terms are explained in the article tempo
where not otherwise specified.
The first movement . . . is a type of alla marcia which advances in canonic imitations. Tranquil at first, it augments little by little and develops into the same kind of triplet motive which marks the opening of the Jupiter Symphony
. Thus this concerto, which has been neglected and ignored for so long, contains from its first notes elements of grandeur and dramatic power.
The Andante is a tender and lyrical dialogue between the soloist and the strings, the latter supported from time to time by oboes, bassoons, and horns. Mozart seems to have originally intended, judging from sketches (Girdlestone, Mozart and his Piano Concertos
) a C minor slow movement for this concerto - perhaps he judged it not appropriate for the mood of the work.
But above all it is the Finale, a frolicsome dance in 6/8, which deserves our fullest attention. A letter of Mozart to his father from Vienna, January 22, 1783, throws much more penetrating and informative light on the subject: 'I shall send the cadenza
s and eingänge
(short extemporized lead-ins), to my dear sister at the first opportunity. I have not yet altered the eingänge in the rondo, for whenever I play this concerto, I always play whatever occurs to me at the moment."
The use of cadenzas at the end of each movement is still common today, while the small fermatas, upon which we come unexpectedly here and there, and most significantly at the eingange , which twice announce the approach of the sublime adagio in C minor, have been virtually ignored since the performances by Mozart himself or by the musicians of his time. At the end of the rondo, Mozart introduces a popular folksong, ingratiating and fresh in mood, against the murmurings of the strings.13
