Each mode has characteristic intervals and chords that give it its distinctive sound. The following is an analysis of each of the seven modern modes. The examples are provided in a key signature with no sharps or flats (scales composed of [[natural note]]s).

====Ionian (I)====
The [[Ionian mode]] is the modern [[major scale]]. The example composed of natural notes begins on C, and is also known as the [[C-major]] scale:

  \time 7/4 c4 d e f g a b c

*'''Tonic [[triad (music)|triad]]''': C major
*'''Tonic [[seventh chord]]''': C<sup>M7</sup>
*'''Dominant triad''': G (in modern tonal thinking, the fifth or dominant [[Degree (music)|scale degree]], which in this case is G, is the next-most important [[Root (chord)|chord root]] after the tonic)
*'''Seventh chord on the dominant''': G<sup>7</sup> (a [[dominant seventh chord]], so-called because of its position in this – and only this – modal scale)

====Dorian (II)====
The [[Dorian mode]] is the second mode. The example composed of natural notes begins on D:

| D || E || F || G || A || B || C || D
|-
! [[Interval (music)|Interval]] from D
| P1 || M2 || m3 || P4 || P5 || M6 || m7 || P8
|}
The Dorian mode is very similar to the modern [[natural minor scale]] (see Aeolian mode below). The only difference with respect to the natural minor scale is in the sixth [[Degree (music)|scale degree]], which is a major sixth (M6) above the tonic, rather than a minor sixth (m6).

*'''Tonic triad''': Dm
*'''Tonic seventh chord''': Dm<sup>7</sup>
*'''Dominant triad''': Am
*'''Seventh chord on the dominant''': Am<sup>7</sup> (a [[minor seventh chord]])

====Phrygian (III)====
The [[Phrygian mode]] is the third mode. The example composed of natural notes starts on E:

\override Score.TimeSignature #'stencil = ##f
\relative c' { 
  \clef treble 
  \time 7/4 e4 f g a b c d e

| E || F || G || A || B || C || D || E
|-
! [[Interval (music)|Interval]] from E
| P1 || m2 || m3 || P4 || P5 || m6 || m7 || P8
|}

The Phrygian mode is very similar to the modern [[natural minor scale]] (see Aeolian mode below). The only difference with respect to the natural minor scale is in the second [[Degree (music)|scale degree]], which is a minor second (m2) above the tonic, rather than a major second (M2).

*'''Tonic triad''': Em
*'''Tonic seventh chord''': Em<sup>7</sup>
*'''Dominant triad''': Bdim
*'''Seventh chord on the dominant''': B<sup>ø7</sup> (a [[half-diminished seventh chord]])

====Lydian (IV)====
The [[Lydian mode]] is the fourth mode. The example composed of natural notes starts on F:
{{Image frame|content=<score sound="1">
{
\override Score.TimeSignature #'stencil = ##f
\relative c' { 
  \clef treble 
  \time 7/4 f4 g a b c d e f
} }
</score>|width=300|caption=The modern [[Lydian mode]] on F}}

{| class="wikitable"
|-
! [[Natural note]]s
| F || G || A || B || C || D || E || F
|-
! [[Interval (music)|Interval]] from F
| P1 || M2 || M3 || A4 || P5 || M6 || M7 || P8
|}

The single tone that differentiates this scale from the [[major scale]] (Ionian mode) is its fourth [[Degree (music)|degree]], which is an augmented fourth (A4) above the tonic (F), rather than a perfect fourth (P4).

*'''Tonic triad''': F
*'''Tonic seventh chord''': F<sup>M7</sup>
*'''Dominant triad''': C
*'''Seventh chord on the dominant''': C<sup>M7</sup> (a [[major seventh chord]])

====Mixolydian (V)====
The [[Mixolydian mode]] is the fifth mode. The example composed of natural notes begins on G:
{{Image frame|content=<score sound="1">
{
\override Score.TimeSignature #'stencil = ##f
\relative c'' { 
  \clef treble 
  \time 7/4 g4 a b c d e f g
} }
</score>|width=300|caption=The modern [[Mixolydian mode]] on G}}

{| class="wikitable"
|-
! [[Natural note]]s
| G || A || B || C || D || E || F || G
|-
! [[Interval (music)|Interval]] from G
| P1 || M2 || M3 || P4 || P5 || M6 || m7 || P8
|}

The single tone that differentiates this scale from the major scale (Ionian mode) is its seventh degree, which is a minor seventh (m7) above the tonic (G), rather than a major seventh (M7). Therefore, the seventh scale degree becomes a [[subtonic]] to the tonic because it is now a whole tone lower than the tonic, in contrast to the seventh degree in the major scale, which is a semitone tone lower than the tonic ([[leading-tone]]).

*'''Tonic triad''': G
*'''Tonic seventh chord''': G<sup>7</sup> (the dominant seventh chord in this mode is the seventh chord built on the tonic degree)
*'''Dominant triad''': Dm
*'''Seventh chord on the dominant''': Dm<sup>7</sup> (a minor seventh chord)

====Aeolian (VI)====
The [[Aeolian mode]] is the sixth mode. It is also called the [[natural minor scale]]. The example composed of natural notes begins on A, and is also known as the [[A minor|A natural-minor]] scale:

{{Image frame|content=<score sound="1">
{
\override Score.TimeSignature #'stencil = ##f
\relative c'' { 
  \clef treble 
  \time 7/4 a4 b c d e f g a
} }
</score>|width=300|caption=The modern [[Aeolian mode]] on A}}

|}

*'''Tonic triad''': Am
*'''Tonic seventh chord''': Am<sup>7</sup>
*'''Dominant triad''': Em
*'''Seventh chord on the dominant''': Em<sup>7</sup> (a minor seventh chord)

====Locrian (VII)====
The [[Locrian mode]] is the seventh mode. The example composed of natural notes begins on B:

{
\override Score.TimeSignature #'stencil = ##f
\relative c'' { 
  \clef treble 
  \time 7/4 b4c d e f g a b

| B || C || D || E || F || G || A || B
|-
! [[Interval (music)|Interval]] from B
| P1 || m2 || m3 || P4 || d5 || m6 || m7 || P8
|}

The distinctive [[Degree (music)|scale degree]] here is the diminished fifth (d5). This makes the tonic triad diminished, so this mode is the only one in which the chords built on the tonic and dominant scale degrees have their roots separated by a diminished, rather than perfect, fifth. Similarly the tonic seventh chord is half-diminished.
*'''Tonic triad''': Bdim or B°
*'''Tonic seventh chord''': Bm<sup>7{{Music|flat}}5</sup> or B<sup>ø7</sup>
*'''Dominant triad''': F
*'''Seventh chord on the dominant''': FM<sup>7</sup> (a major seventh chord)
