Mozart's piano sonata in C major (k545) is recommended.

Mozart's piano sonata in C major (k545) is a piano sonata for beginners. Among Mozart's piano sonatas, it is considered to be the easiest to play. It was completed on June 26th, 1788, which happened to be the day Mozart finished k543 in E flat major, the first of his three symphonies.

the first movement: allegro in c major, sonata form. This is a piece of music filled with joy. The first theme is only four bars, which is extremely simple. Then, there is a musical sentence, and then, accompanied by the left hand, the second theme is played in the dominant tone. After the left hand and the right hand interactively play the broken chord sound pattern, it goes through the end of vibrato connection. The expansion part takes over the sound pattern of the end part of the presentation part, starting from G minor. When entering the reproduction department, the first theme adopted F major in an unusual way, and before the second theme in C major appeared, there was a passage of scale type in the middle. The first movement ends in the sound group of left-handed interaction.

second movement: andante in g major, trilogy. This movement should be played with a cheerful mood. Although the technique is easy, it is difficult to play musically. It should be played with Legato like singing. The main theme is tenderness. After this theme is repeated by variation, it still gently plays a melody in D major that seems to be derived from the main theme. After the repetition of the variation of the main theme, the melody in D major appears in G minor, and after a series of tone sandhi in B flat major, C minor and G minor, the reproduction of the main theme is led out. After the variation, the second movement ends with the coda.

the third movement: Rondo for Allegro, in C major, Rondo. This movement is the most difficult in this sonata. The movement begins with the theme of Rondo. Then there is the first insertion in G major, which is an octave sound form from the theme of Rondo. After the theme of Rondo appeared for the second time, the second insertion of minor appeared, which was also derived from the theme of Rondo. After the theme of Rondo appeared for the third time, it ended with an ending composed of octaves.
