Let’s learn how to form a Dm7 chord on piano. A minor seventh chord is formed by combining the root, minor third, perfect fifth and minor seventh of the major scale. The notes of the D major scale are D – E – F# – G – A – B – C#. Following the minor 7 chord formula 1 – 3b – 5 – 7b, the notes used in a D minor 7 chord are D – F – A – C. While F# and C# are found in the D major scale, in the D minor seventh chord they have been lowered by a semitone and the notes F and C are played.
The D minor seventh chord is commonly written as Dm7, D min7, D -7, and D minor 7.
In terms of intervals, a minor seventh chord is made up of a minor interval, a major interval and a minor interval. For the first minor interval, start on the note, D, skip two semitones, D# and E, and land on the third semitone, F. This is an interval of one and a half steps (3 half steps or tones). For the next interval, the major interval, start on the note F, skip three semitones, F#, G and G# and land on the fourth semitone, A. This is an interval of four half steps ( two steps or tones). For the second minor interval, start on the note A, skip two semitones, A# and B, and land on the third semitone, C. This is an interval of three semitones (one and a half tones or steps).
The Dm7 chord can be played in different voicings and inversions.
Firstly, in root position, the notes of the Dm7 chord is in the sequence D – F – A – C. D is played with finger 1 (thumb), F is played with finger 2, A is played with 3, and C is played with finger 5.
In the first inversion of the Dmin7 chord, the note D is moved up one octave and the sequence of notes becomes F – A – C – D. To play the second inversion of the chord, the note F must be moved up one octave and the sequence of pitches becomes A – C – D – F. Lastly, for the third inversion of the D minor 7 piano chord, the note A must be moved up one octave and the sequence of pitches now becomes C – D – F – A. In every inversion of the chord the notes are the same. The only difference is where the notes are located in the chord.
