A classic jazz ballad that combines elements of jazz and pop music. The song is written in 3/4 time, which gives it a waltz character. The main key is F-major (F major). The harmonic structure of the song includes many chord progressions typical of jazz, such as II-V-I and III-VI-II-V. These progressions create a rich harmonic texture and allow musicians to improvise. Sometimes replacing the chord with b5 is used, which adds an interesting chromaticism to the harmony. Wind instruments such as saxophone or trumpet, as well as guitar, are added. Not only is it a beautiful melody, but it also has a complex harmonic structure.
