While you listen

A melody above the motion.

Listen beneath the familiar tune. A gentle stream of repeated notes keeps the music moving, even when the melody seems to float.

Let the strings begin: The orchestra sets the scene before the piano enters.
Follow one piano, two staves: The melody and accompaniment share a colour. Select either staff to follow the whole instrument.
Hear the light change: Warm phrases pass through darker harmonies before finding their way home.

Behind the music

In Vienna, Mozart was both a composer and a celebrated pianist. His concertos gave him new music to bring to the stage. He completed this one on 9 March 1785; its first performance followed the next day at the Burgtheater.

This is the complete Andante, the concerto’s second movement. Its quiet surface rests on a continually moving triplet accompaniment.

Recording, score & sources

Wolfgang Amadeus Mozart · Piano Concerto No. 21 in C major, K. 467 · II. Andante.

Robert Casadesus, piano; the Philharmonic-Symphony Orchestra of New York, conducted by Charles Munch. This historical recording comes from the University of the Arts Helsinki’s Taju archive, which dates the release to approximately 1953–1956 and labels it Public Domain Mark 1.0. This local preview is for evaluation; distribution rights vary by country.

MusicXML: Yiako187’s transcription, distributed in PDMX as CC0, with six individually encoded wind parts from MuseData’s NMA-derived source. All 104 bars are present. Thirteen instruments occupy fourteen staves; each oboe, bassoon, and horn has its own row.

The separate wind source’s redistribution terms still need review. Its files are not covered by the PDMX license. This player is a local preparation preview.

The original file is preserved. Measured triplet repeats are written out; hidden MIDI realizations are omitted, and explicitly tied hidden continuations are joined. Trills and grace notes remain notation, without invented individual attacks. The viewing score uses a fixed clef for each staff; original clef changes remain in the source.

This is a preparation preview. Edition differences and the recording alignment still require musical review before library acceptance.

Background sources: the Mozarteum’s Köchel catalogue and LA Phil’s programme notes.
