The piano music for the song "When I Was Your Man" by Bruno Mars has been transcribed and is available to purchase. It is in the key of C Major. The single version of the song is composed in 4/4 time and has a tempo of without accelerando or ritardando.
The piece starts out with a simple two bar lead-in phrase before the first verse begins. The first verse is composed of seven measures of chords in the right hand and a rhythmic accompaniment in the left hand. After the verse, the chorus begins with an upbeat and positive sounding section that includes chords and an eighth note triplet pattern in the left hand. The chorus is then followed by the bridge, which contains a characteristic sixteen bar pattern in 4/4 time. This is followed by a well-crafted turnaround in the key of C major that leads back to the chorus.
The main melody in the right hand is composed mostly of ascending and descending scales. The left hand structure is composed of a constant eighth note pattern that is punctuated by chords. A wealth of improvisational opportunity is also available in many sections of the song, including the bridge and are also based in C Major.
The sheet music is widely available and can be purchased from many different sources, both online and in sheet music stores.
