According to many people there are 12 "common" chords, however, there are many chord combinations. A chord can be any two or more notes, so a chord can have 2, 3, 4, 5, 6, or more notes. With that number of combinations, chord possibilities are almost limitless.
The notes in the chord D minor flat 5, or D diminished, are D F A-flat.
The first, third, fifth, and seventh note derived from the C major scale, so: C-E-G-B for a major seventh chord (Cmaj7) and the seventh note flattened to Bb or B flat in the C7 chord commonly used in pop/blues as a final chord but in most classical music to be resolved in F.
Chord equation: y = x+5 Circle equation: x^2 +4x +y^2 -18y +59 = 0 Both equations intersect at: (-1, 4) and (3, 8) which are the endpoints of the chord Midpoint of the chord: (1, 6) Slope of chord: 1 Perpendicular slope: -1 Perpendicular bisector equation: y-6 = -(x-1) => y = -x+7
Form a simultaneous equation with chord and circle and by solving it:- Chord makes contact with circle at: (-1, 4) and (3, 8) Midpoint of chord: (1, 6) Slope of chord: 1 Slope of perpendicular bisector: -1 Perpendicular bisector equation: y-6 = -(x-1) => y = -x+7
A chord is formed when multiple pitches (notes on a musical instrument) are placed together on a staff (a sheet of music). Chords come in a lot of different varieties, including (but not limited to): Major chords, minor chords, diminished chords, augmented chords, seventh chords, and Neapolitan chords. To develop a chord, one simply takes two or more notes from the staff and (in the case of piano or string instruments) plays them simultaneously. For instance: C-E-G is a C Major triad (triad is just a fancy term for a chord with three notes). F-A-C is an F Major triad. When you listen to music, the harmony parts behind the leading melody are generally chords. Rock groups like "Queen" are notorious for having a lot of harmonized parts in their music. Every song from every genre has a chord progression - meaning one chord follows the next in a pattern. Rock is generally I-IV-V-I (Roman Numerals denote the type of chord used) used over and over.
Equation of circle: x^2 +4x +y^2 -18y +59 = 0 Completing the squares: (x+2)^2 +(y-9)^2 = 26 Equation of chord: y = x+5 Endpoints of chord: (-1, 4) and (3, 8) Midpoint of chord: (1, 6) Center of circle: (-2, 9) Slope of chord: 1 Slope of radius: -1 Perpendicular bisector equation of chord: y-6 = -1(x-1) => y =-x+7
Chord equation: y = x+5 Circle equation: x^2 +4x +y^2 -18y +59 = 0 Chord end points: (-1, 4) and (3, 8) Chord midpoint: (1, 6) Perpendicular slope: -1 Perpendicular bisector equation: y-6 = -1(x-1) => y = -x+7
generally, 3 to 5 notes at one time is called a chord. Two notes together is just an interval of some sort, depending upon how close the notes are together on a piano (second, third, fourth, fifth, sixth or seventh)
A series of notes sounded simulanteously- for example a C- Chord which is, on a Piano- fingered 1-3-5 starting at Middle C. Chord in Math might have to deal with a section of a bridge or an airplane wing- it has a different application than the musical sense. As music is mathematical- I have given the tonal variety first.
A 12 bar blues is a song with "12 Bars". It starts with the 1 chord in any given key. Typically the 1 chord is kept for 4 measures. Then the 4 chord for 2 measures. Then back to the 1 chord for 2 more. Then end with 5 chord, 4 chord, then the 1 chord for the last two measures. You can subsitute the second chord for the 4 and the last for 5 if you are going to a turn around.
