In the key of C major, the I major 7 chord is "C, E, G, B," the iii chord ("III–7" [11]) is E minor 7 ("E, G, B, D") and the vi minor 7 chord is A minor 7 ("A, C, E, G"). Both of the tonic substitute chords use notes from the tonic chord, which means that they usually support a melody originally designed for the tonic (I) chord.
Beethoven's Piano Sonata in E Minor, Op. 90, contains a passage where a B ♭ becomes an A ♯, altering its musical function. The first two bars of the following passage unfold a descending B ♭ major scale. Immediately following this, the B ♭ s become A ♯ s, the leading tone of B minor: Beethoven Sonata in E Minor Op. 90, first movement ...
In comparison with standard tuning, each major-chord open-string tuning reinforces different "overtones and can actually make the guitar sound louder and more resonant". [3] To explain this resonance and strengthened sound, the example of the overtones on C has been used; and C's overtones is a standard example for explaining the sequence of ...
The fourth degree in major may be substituted for a seventh chord to create a "bluesy" sound. In a progression going up a fourth, if the first chord is a minor seventh chord, it can also be substituted for a seventh chord; a relative second degree can also be added before it to create a ii–V–I turnaround. (A sole minor seventh or seventh ...
This allows for the note range of B standard tuning without transposing E standard guitar chords down two and a half steps down. Baritone 7-string guitars are available which features a longer scale-length allowing it to be tuned to a lower range. Standard 7-string tuning – B'-E-A-d-g-b-e' Standard tuning for a seven-string guitar.
Modal tunings are open tunings in which the open strings of the guitar do not produce a tertian (i.e., major or minor, or variants thereof) chord. The strings may be tuned to exclusively present a single interval (all fourths; all fifths; etc.) or they may be tuned to a non-tertian chord (unresolved suspensions such as E–A–B–E–A–E ...
In standard jazz harmony, tritone substitution works because the two chords share two pitches that themselves are a tritone apart: namely, the third and the seventh of the chord, albeit reversed. [8] In a G 7 chord, the third is B and the seventh is F; in its tritone substitution, D ♭ 7, the third is F and the seventh is C ♭ (enharmonically ...
Inverted major and minor chords can be played on two frets in M3 tuning. [76] [77] In standard tuning, the shape of inversions depends on the involvement of the irregular major third, and can involve four frets. [78] It is a challenge to adapt conventional guitar chords to new standard tuning, which is based on all-fifths tuning. [j]
