Means it's a chord were C is the fundamental note. The fundamental note, is the note from were the chord is constructed.
So if it's a C major chord, it could be
C E G or C E G B
Not sure what you mean, but if you mean A/C, that means an A chord played over a C in the bass.
No chord
309.5
Not sure what you mean. If you mean a suspension chord, that is a chord made up of the I, IV, and V of a scale. For instance, a Csus is C, F, G. There is also a Sus 2 chord, which is the I, II, and V of a scale. A Csus2 would be C, D, and G. However, that is normally just called a 2 chord.
I always play an A-chord, with a C in the bass. I should note an A-chord with a bass-C sounds rather dissonant. An A-minor/C or a A/C# would be more logical.
A C and F chord
A chord with the fourth in it. C fourth chord is C F and A, although, it's not really called a fourth, it's called a suspension or suspended chord.
If you mean what are the notes in and an A minor chord, the notes are A, C, and E.
Csus4 means C suspended4th. Its a chord use in Music
The term, "root" in Musical terms means the note that the rest of a chord is based around. For example, a C major chord which consists of the notes C, E and G would have a root note of C as it the note that allows the rest of a chord to follow. It is always the first note of any chord.
That is called the "base" of the chord. Try not to get this word confused with "root," which is the lowest note of the chord if it is in root position. Root position is when the chord is built up in thirds. Ex: C, E and G make up the C chord and the root of the chord "C" is also the base note. If this same C chord is mixed around so that G is the lowest note then higher in order is C and then E, then G would be the base note of the chord.
You add an extra note into the original minor chord. An A minor chord consists of the notes A - C - E. The Am7 chord consists of A - C - E - G
