In music , the subdominant is the fourth tonal degree ( ) of the diatonic scale . It is so called because it is the same distance below the tonic as the dominant is above the tonic – in other words, the tonic is the dominant of the subdominant. It also happens to be the note one step below the dominant. In the movable do solfège system, the subdominant note is sung as fa .
20-452: The triad built on the subdominant note is called the subdominant chord . In Roman numeral analysis , the subdominant chord is typically symbolized by the Roman numeral "IV" in a major key , indicating that the chord is a major triad . In a minor key, it is symbolized by "iv", indicating that the chord is a minor triad . In very much conventionally tonal music , harmonic analysis will reveal
40-427: A tonic in a song or some other piece of music. That is, a song or other vocal or instrumental piece can be in the key of C major or A minor, but a song or some other piece cannot be in the key of B diminished or F augmented (although songs or other pieces might include these triads within the triad progression, typically in a temporary, passing role ). Three of these four kinds of triads are found in
60-509: A triad is a set of three notes (or " pitch classes ") that can be stacked vertically in thirds. Triads are the most common chords in Western music. When stacked in thirds, notes produce triads. The triad's members, from lowest-pitched tone to highest, are called: Some 20th-century theorists, notably Howard Hanson , Carlton Gamer , and Joseph Schillinger expand the term to refer to any combination of three different pitches, regardless of
80-444: A " tertian triad". The root of a triad, together with the degree of the scale to which it corresponds, primarily determine its function. Secondarily, a triad's function is determined by its quality: major , minor , diminished or augmented . Major and minor triads are the most commonly used triad qualities in Western classical , popular and traditional music . In standard tonal music , only major and minor triads can be used as
100-450: A C major triad uses the notes C–E–G. This spells a triad by skipping over D and F. While the interval from each note to the one above it is a third, the quality of those thirds varies depending on the quality of the triad: The above definitions spell out the interval of each note above the root. Since triads are constructed of stacked thirds, they can be alternatively defined as follows: Triads appear in close or open positions. "When
120-430: A broad prevalence of the primary (often triadic) harmonies: tonic, dominant, and subdominant (i.e., I and its chief auxiliaries a 5th removed), and especially the first two of these. These chords may also appear as seventh chords : in major, as IV, or in minor as iv or sometimes IV: A cadential subdominant chord followed by a tonic chord produces the so-called plagal cadence. As with other chords which often precede
140-530: A good idea to have the term 'tone center' refer to the more general class of which 'tonics' (or tone centers in tonal contexts) could be regarded as a subclass." Thus, a pitch center may function referentially or contextually in an atonal context, often acting as an axis or line of symmetry in an interval cycle . The term pitch centricity was coined by Arthur Berger in his "Problems of Pitch Organization in Stravinsky". According to Walter Piston , "the idea of
160-456: Is distinguished from the root , which is the reference note of a chord, rather than that of the scale. In music of the common practice period , the tonic center was the most important of all the different tone centers which a composer used in a piece of music, with most pieces beginning and ending on the tonic, usually modulating to the dominant (the fifth scale degree above the tonic, or the fourth below it) in between. Two parallel keys have
180-470: Is typically symbolized by the Roman numeral "I" if it is major and by "i" if it is minor. In very much conventionally tonal music, harmonic analysis will reveal a broad prevalence of the primary (often triadic) harmonies: tonic, dominant , and subdominant (i.e., I and its chief auxiliaries a 5th removed), and especially the first two of these. These chords may also appear as seventh chords : in major, as I , or in minor as i or rarely i : The tonic
200-426: The dominant, subdominant chords typically have predominant function . In Riemannian theory , it is considered to balance the dominant around the tonic (being as far below the tonic as the dominant is above). The term subdominant may also refer to a relationship of musical keys. For example, relative to the key of C major, the key of F major is the subdominant. Music which modulates (changes key) often modulates to
220-484: The first, fourth, and fifth degrees (respectively) of the diatonic scale, and the triads are accordingly symbolized I, IV, and V. Primary triads "express function clearly and unambiguously." The other triads in diatonic keys include the supertonic , mediant , submediant , and leading-tone , whose roots are the second, third, sixth, and seventh degrees (respectively) of the diatonic scale, symbolized ii, iii, vi, and vii . They function as auxiliary or supportive triads to

#1733086119873240-412: The intervals. Schillinger defined triads as "A structure in harmony of but three parts; conventionally, but not necessarily, the familiar triad of ordinary diatonic harmony." The word used by other theorists for this more general concept is " trichord ". Others use the term to refer to combinations apparently stacked by other intervals, as in " quartal triad"; a combination stacked in thirds is then called
260-556: The late Renaissance music era, and especially during the Baroque music era (1600–1750), Western art music shifted from a more "horizontal" contrapuntal approach (in which multiple, independent melody lines were interwoven ) toward progressions , which are sequences of triads. The progression approach, which was the foundation of the Baroque-era basso continuo accompaniment, required a more "vertical" approach, thus relying more heavily on
280-413: The major (or diatonic) scale. In popular music and 18th-century classical music, major and minor triads are considered consonant and stable, and diminished and augmented triads are considered dissonant and unstable. When we consider musical works we find that the triad is ever-present and that the interpolated dissonances have no other purpose than to effect the continuous variation of the triad. In
300-399: The primary triads. Tonic (music) In music , the tonic is the first scale degree ( [REDACTED] ) of the diatonic scale (the first note of a scale) and the tonal center or final resolution tone that is commonly used in the final cadence in tonal (musical key -based) classical music , popular music , and traditional music . In the movable do solfège system,
320-544: The same tonic. For example, in both C major and C minor, the tonic is C. However, relative keys (two different scales that share a key signature ) have different tonics. For example, C major and A minor share a key signature that feature no sharps or flats, despite having different tonic pitches (C and A, respectively). The term tonic may be reserved exclusively for use in tonal contexts while tonal center or pitch center may be used in post-tonal and atonal music: "For purposes of non-tonal centric music, it might be
340-515: The subdominant when the leading tone is lowered by half step to the subtonic (B to B ♭ in the key of C). Modulation to the subdominant key often creates a sense of musical relaxation, as opposed to modulation to the dominant (fifth note of the scale), which increases tension.

360-469: The three upper voices are as close together as possible, the spacing is described as close position or close harmony. [...] The other arrangements [...] are called open position or open harmony." Each triad found in a diatonic (single-scale-based) key corresponds to a particular diatonic function . Functional harmony tends to rely heavily on the primary triads : triads built on the tonic , subdominant , and dominant degrees. The roots of these triads are
380-408: The tonic note is sung as do . More generally, the tonic is the note upon which all other notes of a piece are hierarchically referenced. Scales are named after their tonics: for instance, the tonic of the C major scale is the note C . The triad formed on the tonic note, the tonic chord , is thus the most significant chord in these styles of music. In Roman numeral analysis , the tonic chord
400-421: The triad as the basic building block of functional harmony . The primacy of the triad in Western music was first theorized by Gioseffo Zarlino (1500s), and the term "harmonic triad" was coined by Johannes Lippius in his Synopsis musicae novae (1612). Triads (or any other tertian chords) are built by superimposing every other note of a diatonic scale (e.g., standard major or minor scale). For example,
