The perception of the key of G major in Bach's works conveys a very lively, bright, and refreshing impression, and it is also powerful. Its brightness is evident when one recalls the Inventions, Sinfonias, or the Well-Tempered Clavier.

In the first movement of this concerto, the note values become smaller towards the end, which means the tension increases as it progresses. It is presupposed that the tutti and solo sections are played with awareness, with the tutti being loud and the solo being restrained. Strive for a performance where even someone unfamiliar with the piece can clearly distinguish between the tutti and solo sections.

The color changes with a modulation to E minor midway. For the performer, which key, E minor or G major, feels more tense? Try to create a difference as you perceive it. After this, a harmonic sequence begins, returning through D minor, C major, and finally back to G major. Apply differences in dynamics and tone quality for each key. Bach's unique sense of humor can be felt around this point. Play cheerfully, energetically, with clear direction, and with brilliance.
