The Piano Concerto No. 14 in E♭ major, K. 449, is a composition by Wolfgang Amadeus Mozart, written in Vienna in 1784.

The Piano Concerto in E-flat is the first work that Mozart entered into a notebook of his music which he kept for the rest of his life, indicating the main themes and dates of completion of each work. From this primary source, we learn that he finished the concerto on February 9, 1784.

In the same year, he wrote several concertos in succession, and in a letter to his father that May, wrote of the 15th and 16th concertos (K. 450 and 451) that he "could not choose between them," but that "the one in E-flat [No. 14] does not belong at all to the same category. It is one of a quite peculiar kind...". The 14th is regarded as being the first of the mature series of concertos Mozart wrote, and indeed, commentators such as Girdlestone and Hutchings^{[This quote needs a citation]} valued it as one of the best, particularly as all three movements are of the highest standard.

Like his earlier concertos, Nos. 12, K. 414, and 13, K. 415, Mozart wrote the E-flat Piano Concerto for his subscription concerts, "either with a large orchestra with wind instruments or merely a quattro" [with string quartet].^[1]

The concerto is scored for 2 oboes, 2 horns and strings, and it is in three movements:

The first movement begins in a ³
₄ time signature, an unusual feature among Mozart's 27 piano concertos. Among them only this, the fourth, the eleventh, and twenty-fourth open with a movement in ³
₄. It is also traditional, in the tutti of a classical concerto, for there to be little key adventuring. There are several reasons for this, but the upshot is that, the less this is true, the harder it becomes to distinguish the tutti from the opening of a classical-era symphony.

The first phrase of this concerto begins ambiguously. A unison E♭ followed by a C, then a G, is followed by the dominant chord's leading tone (A♮) trilled up to the dominant, B♭. This progression seems to suggest a dominant cadence in the dominant key of B♭. In other words, C minor to F to B♭ (ii – V – I in B♭). There is an immediate modulation, through a fiery C-minor passage, into B♭ major. Here a possible second theme is heard, played by strings, winds not coming in until its later strain (near the modulation back into E♭).

The first movement ventures off from the normal conception of the concerto. Usually, when it comes time for the cadenza at the end of the recapitulation, the soloists will have a cadential trill on the tonic after which the orchestra will play part of the ritornello leading to the cadential I⁶
₄, at which point the soloists performs the cadenza. However, instead of the trill being accompanied by strings, it is interrupted by them on the second beat and ends up resolving to C minor. Shortly thereafter, however, the I⁶
₄ arrives and the cadenza begins and everything continues on as normal.

(Girdlestone 1964, p. 187) writes that the gait of this finale is "neither that of a gallop, nor of a race, nor even of a dance, but just of a swinging walk, swift and regular, and the virtue of its refrain, with its sketchy outline and its 'sillabato' diction... rests in its rhythm rather than in its melody." Further, he notes that while this rondo can be divided into contrasting sections, the appearance on the page is very different from what falls on the ear, which is almost monothematic: "When, score in hand, one notes each return of the first subject... it is possible to pick out the four expositions of the [rondo] refrain and the three couplets... but on hearing it one's impression is that the refrain never leaves the stage."
