Five and one half steps down from standard. Octave Tuning – B"-E'-A'-D-G-B-e Six full steps (one octave) down from standard tuning. The open C tuning for 7-string guitar was Devin Townsend's preferred tuning for the extreme metal band Strapping Young Lad (GCGCGCE), used on their last two albums.
The graphical representation of Vogel's Tonnetz is limited to the three dimensions for fifths, thirds, and seventh. In this representation tones separated by one or several octaves are depicted on the same nodes. The illustration shows the chord which is the most frequent 4-note chord in western music: the dominant seventh.
The guitar is a transposing instrument; that is, music for guitars is notated one octave higher than the true pitch. This is to reduce the need for ledger lines in music written for the instrument, and thus simplify the reading of notes when playing the guitar. [5]
[50] [h] The standard-tuning implementation of a C7 chord is a second-inversion C7 drop 2 chord, in which the second highest note in a second inversion of the C7 chord is lowered by an octave. [ 50 ] [ 52 ] [ 53 ] Drop-two chords are used for sevenths chords besides the major–minor seventh with dominant function, [ 54 ] which are discussed in ...
Letter notation is the most common way of indicating chords for accompaniment, such as guitar chords, for example B ♭ 7. The bass note may be specified after a /, for example C/G is a C major chord with a G bass. Where a capo is indicated, there is little standardisation.
M3 simplifies the voicing of chords in close harmony, but it makes certain common voicings in open harmony more difficult, or even impossible; M3 facilitates moving 3- and 4-note chords up or down an octave, but it makes the fingerings for 5- and 6-note multi-octave chords more complex and awkward.
12-tone equal temperament chromatic scale on C, one full octave ascending, notated only with sharps. Play ascending and descending ⓘ. 12 equal temperament (12-ET) [a] is the musical system that divides the octave into 12 parts, all of which are equally tempered (equally spaced) on a logarithmic scale, with a ratio equal to the 12th root of 2 (≈ 1.05946).
To go from A 4 up two semitones (one whole tone) to B 4, multiply 440 twice by the twelfth root of two (or once by the sixth root of two, approximately 1.122462). To go from A 4 up three semitones to C 5 (a minor third ), multiply 440 Hz three times by the twelfth root of two (or once by the fourth root of two, approximately 1.189207).
