Similar to Piano Concertos Nos. 1-4, these are arrangements of other composers' piano sonatas. The original works for these concertos are the second, third, and fourth sonatas from Johann Christian Bach (1735-82)'s Six Piano Sonatas, Op. 5.

Johann Christian Bach was the youngest son of J. S. Bach and is known as 'the London Bach' due to the city where he ultimately flourished. Having studied extensively in Milan, his music is characterized by an elegant, bright, and gallant Italianate style, and is believed to have profoundly influenced Mozart. Mozart became acquainted with him during his stay in London from 1764 to the following year, when Mozart was eight years old.

These three piano concertos (K. 107) feature a simple instrumentation of solo piano (or harpsichord), two violin parts, and bass, retaining the atmosphere of the original works without significant alteration. The first concerto consists of a cheerful first movement that utilizes the bright key of D major, a soft slow movement with harmonious interplay between strings and solo piano, and a minuet movement primarily led by the solo piano.

Of the three concertos, only the first and second movements of the first concerto in D major have cadenzas preserved by Mozart.
