What is the tonal center of a piece of music?

In tonality, the tonic (tonal center) is the tone of complete relaxation and stability, the target toward which other tones lead. The cadence (coming to rest point) in which the dominant chord or dominant seventh chord resolves to the tonic chord plays an important role in establishing the tonality of a piece.

How do you identify tonality?

The tonality of the song will be one degree above the last sharp. In the example above, the last sharp was in the C note, so the tonality is D major. Note: a degree, in this case, is the next note of the line or space. If you want to know the relative minor tonality, just take a degree below that last sharp.

What is the system where the musical piece is based on key center?

Key, in music, a system of functionally related chords deriving from the major and minor scales, with a central note, called the tonic (or keynote). The central chord is the tonic triad, which is built on the tonic note. Any of the 12 tones of the chromatic scale can serve as the tonic of a key.
