Mozart composed two Duos for violin and viola, No.1 in G major, KV423, and No.2 in Bb major, KV424. The close friendship between Joseph Haydn (1732-1809) and Mozart is very famous. Mozart was very close to also Joseph’s younger brother, Michael Haydn (1737-1806). In 1783, Michael Haydn was ill and incapacitated to compose two Duos for violin and viola. He had finished four duos to order for the archbishop of Salzburg, however he the order was six. Mozart composed two inspired duos, KV423 and KV424, to save Michael Haydn.

Number. 2 (KV424) consists of the following three movements, I. Adagio - Allegro, II. Andante cantabile, III. Thema con variazioni: Andante grazioso.

When I played the viola part, I needed a score for the second movement. Viola player should know all the notes of violin part. Otherwise violinist could not sing freely. Our sheet music of the viola part is score-style (the second movement) which contains the violin part. The other parts contain enough cue-notes to help players.

Note: about 3rd beat of bar 7 in Viola part. In this score, tones are Es/D/Es/F/G/As/G/F according to Neue Mozart-Ausgabe by Bärenreiter-Verlag. There are the other performances based on the other music notes, E/D/E/F/G/A/G/F or Es/D/Es/F/G/A/G/F.

Which method of viewing music should I use?

Score Exchange has two methods to display previews of music: seView which uses regular html and javascipt and the Scorch plug-in from Avid which needs to be downloaded and installed onto your computer. Both have advantages and disadvantages:

seView

seView, is the most compatible option. You should be able to view music on all modern web browsers including most mobile devices. Even if your device does not support javascript you should still be able to preview at least page one of the music.

You do not need to install any additional software to use seView.

Scorch

Scorch is a free plug-in from Avid for displaying and printing music. It can also play the music that you're seeing. As modern web browsers are updated, Scorch is no longer compatible with many browsers. Scorch has never been compatible with mobile devices and some web browsers on Mac computers.

If your web browser does not install Scorch automatically, you can click here to download and install scorch manually.
