Learn the D Sharp Diminished 7th Chord

d sharp diminished

D Sharp diminished is a 7th chord that features a distinct and dissonant sound, formed from taking the 1st, 3rd and flat 5th notes from D# major scale to form it.

This table illustrates the note interval qualities needed to form this chord, along with short notation and fingerings on a piano diagram above.


A diminished scale is a type of symmetrical scale consisting of only four notes that is repeated along a tonal and semitonal cycle, similar to what would occur with either major or minor scales, except with half as many tones and semitones. It provides a great way to construct chords by creating numerous different triads.

When playing diminished chords, it is essential to consider how their underlying scale will alter their sound. Diminished chords often possess dissonant qualities which may cause issues when played alongside other chords – this is due to how its intervals between chord notes have an impact.

Let’s use an example to better grasp this point: the D sharp diminished 7th chord is constructed by using notes D#, F# and A from the D sharp diminished scale and is composed of these intervals and names of notes in its construction. To gain more insight, let’s also review its scale name – for this scale name will give us an understanding of its function as well.

Step one in determining a chord’s shape is identifying its root note – in this instance D#. Once we know this note’s identity, we can use note intervals to form the rest of the chord and invert each inversion accordingly, using similar processes for tones and semitones.

This step illustrates a D-sharp diminished 7th inversion on piano, treble clef and bass clef. This chord contains 4 notes: F#, A#, C and D#.

The second step of selecting an appropriate auxiliary diminished scale for any chord is choosing a suitable auxiliary diminished scale. Auxiliary diminished scales are similar to diatonic scales but contain additional notes than standard diminished scales – thus making auxiliary diminished scales suitable for creating progressions over altered or dominant 7th chords, as well as other types of seventh chords.


Triads are an integral chord type and one of the primary reasons to learn guitar. Triads provide an essential framework for more complex chord progressions while adding character and versatility to your sound. In addition to their obvious harmonic power, triads are easy to play and make an excellent starting point for improvisation. Triads form part of any major scale and will quickly become familiar to anyone familiar with playing guitar for some time.

Triads, which consist of three notes from the same scale, can either be major, minor, or diminished in quality depending on which intervals it contains. We determine this by first looking at its root note (note interval number 1) before considering its other two notes that make up its chord. An augmented chord will have its Roman numeral for its root note marked with an “o”, while for diminished chords an upper-case Roman numeral with “d” is attached instead of an “o”.

Triads consist of three notes called their roots, middle, and fifth notes; with the root note serving as its lowest note and generic third above that serving as its middle note respectively – these three notes being known collectively as diatonic chords that allow us to build them in all keys.

Triads can also be inverted, which allows for their playability from different parts of the fretboard without losing their integrity. To invert a triad, start from its root note and move up or down in scale until you find its other two notes – it may help muting lower strings (e, b and g strings) temporarily to avoid accidentals; alternatively try playing upstrokes one string at a time until all strings have been covered with downstrokes to finish all three strings off at once!


When learning the d sharp diminished chord, it’s essential to understand how intervals affect it. Intervals are distances between notes on a staff that can either be perfect, minor, augmented, or diminished; furthermore they are classified by number of scale steps they cover (i.e. unisons, fourths, fifths and octaves for small intervals, while major, augmented and diminished intervals may encompass larger distances).

There are two factors that determine whether an interval is perfect, major or augmented: its size and quality. To measure its size, count the lines and spaces between notes on a staff (e.g. between C and F is one fourth); when measuring an interval size disregard key signatures, clefs or accidentals.

To determine the quality of an interval, one needs to look at its higher note and observe whether or not it falls in its major scale; if so, this indicates a perfect interval; otherwise it’s called minor; and if an otherwise perfect interval appears one half step larger than expected in its major scale (an augmented interval), then its quality has also been diminished.

Smaller intervals follow a similar methodology; however, their sizes can be altered by either lowering or raising the top note with accidentals; this will either decrease or expand its size accordingly.

To reduce an augmented interval, one needs to lower both top note and bottom note by one half tone – for instance the interval from F to C would be considered an augmented fifth as it’s one half step bigger than what would appear in C major scale; similarly G to A is considered diminished fifth as it’s half step smaller than what would appear in G major scale; using this technique you can create chord progressions which are interesting while adding tension – for instance Noel Gallagher uses G diminished chord before switching over to A minor chord which gives his song “Don’t Look Back”, giving bridge section more emotional sound as well as adding emotions as it adds tension into his song “Don’t Look Back”.


When playing diminished scales on piano it’s essential that fingerings allow for fluent execution, making practice simpler and avoiding mistakes easier. If unsure, consult a scale diagram as a reference point for proper fingerings.

As a general guideline, it is wise to avoid placing fingers 1 and 5 on black keys when playing quickly; using these fingers on black notes could impede your rhythmic flow and slow you down considerably. Of course, playing music still requires using all five fingers on black notes if necessary – just practice slowly so as to prevent making any errors!

Another consideration is pitch. For instance, when playing diminished scale on keyboard it has a sharper pitch than when played on saxophone and its notes are closer together than those of major scale.

Due to differences in pitch and timbre, it becomes more challenging for listeners to detect diminished scale when played on a saxophone. Furthermore, different fingering techniques produce different tonalities which may create distinct tones used as effects.

A d sharp diminished scale may help resolve minor chords, although it doesn’t always work. Instead, ascending diminished should be used; both have tritones but only the ascending diminished has tonal qualities while its counterpart has chromatic ones.

Some pianists use d sharp diminished licks to add tension over altered chords, such as b9/b13. Licks can also be placed symmetrically either side of the neck to add dynamic elements to a piece.
