For example, in a piece in the key of C major, the ii chord is D minor, because D is the second scale degree in a C major scale. The D is minor because to construct a triad over D using only the pitches available in the key of C major—i.e. no sharps, no flats—the triad must be minor—the individual notes D, F and A. The V/ii chord is composed of the pitches in a V chord in the key of ii (key of D minor). The pitches used in a V/ii in this example include the notes A, C# and E (creating an A major chord). In the key of D minor, an A major chord is the dominant chord. In the key of C major, C sharp is an accidental. One can often find examples of tonicization by looking for accidentals, as there are always accidentals involved in tonicization. However, it is important to note that the opposite is not true—just because there is an accidental does not mean that it is definitely a case of tonicization.
