A chord refers to a group of sounds with a certain interval relationship, that is, three or more tones are combined vertically according to the superposition relationship of third or non-third, which is called chord.
Thirds usually have a third chord (a three-note chord), a seventh-chord (a four-note chord), a ninth chord (five notes), an eleventh chord (six notes), and a thirteenth chord (seven notes). Non-third chords, usually are: hanging chords, strong chords (i.e., fifth chords), etc.
"Piano chords" refer to two or more notes played simultaneously on a piano that combine to form a harmonic effect. There are many types of chords on the piano that can be categorized according to different interval relationships and playing styles. Here are some common piano chords and their examples:
Major third chord: Composed of root notes, major thirds, and pure fifths. For example, in C major, C-E-G is a major triad.
Minor third chord: Consists of a root note, a minor third, and a pure fifth. For example, in C minor, C-EB-G is a minor triad.
Seventh chord: consists of root notes, major thirds, pure fifths, and minor sevenths. For example, in C major, G-B-D-F is a genus seventh chord.
Semi-reduced seventh chord: consists of a root note, a minor third, a pure fifth, and a minor seventh. For example, in C major, b-d-f-ab is a semi-minus seventh chord.
Major Seventh Chord: Consists of root notes, major thirds, pure fifths, and major sevenths. For example, in C major, C-E-G-B is a major seventh chord.

In addition to these common piano chords mentioned above, there are many other types of chords, such as increased thirds, reduced thirds, minor major sevenths, etc. Each of these chords has its own unique acoustic effects and emotional colors, and can be widely used in different styles.
