Sonata In G Major, K. 391, L. 79, P. 364: Educational Piano

K. 391 combines approachable harmonic language with genuine keyboard writing that reveals something new on each practice session. The three-page scope feels substantial without becoming overwhelming, making it ideal for building repertoire breadth in an intermediate student's annual program.

Bright, articulate, and conversational. The G major tonality keeps the piece buoyant, while the harmonic language avoids predictability; you encounter moments that feel fresh and slightly unexpected even when the surface remains elegant. There is a sense of discovery as the piece unfolds, as if the composer is thinking alongside the player.

Intermediate pianists ready to move beyond five-finger patterns and Alberti bass into genuine two-part writing and hand independence. This works well for students preparing for exams, competition festivals, or simply building a library of Baroque keyboard repertoire that challenges without discouraging.

• Clarify the independence between hands by practicing the passages with hand crossings at a slow tempo first; Scarlatti's notation often requires the player to visualize which hand plays which note rather than follow traditional staff position alone.
• Shape each phrase as if you are singing; the melodies have a conversational quality that disappears if you treat rhythmic subdivisions as equally important.
• The ornaments (if present in this edition) serve structural purposes, not decoration; resist the urge to rush through them or add extra ones beyond what is marked.

Pair this with a later Classical sonata to show the evolution from Baroque keyboard writing into the Classical period; the contrast in approach to form and texture is instructive for audiences and students alike. It also works beautifully as a recital opener because the three-page length and bright tonality establish focus without dominating the program's center.

• Hand independence and crossing
• Two-part contrapuntal thinking
• Baroque ornament execution (if included in edition)
• Tonal clarity across register shifts
• Phrase shaping in non-sonata-form structures
• Reading original Baroque keyboard notation conventions
