CROSS MATRIX I. For Upright Piano

II. For Flute

Op. 0 no.1

NOTE

This composition contains two movements. The first movement is written for upright piano (however, it can also be played in grand piano), and the second for flute. The material of this composition basically comes from three pre-designed tetrachords, which use the whole twelve tones:�

Extract the first, third, fifth and seventh notes in the harmonic series of every note in these three tetrachords:

A matrix of tetrachords, which come from the harmonic series above, can be built:

�

This matrix is also the direct material of the 1st and 2nd movements. In the 1st movement, the tetrachords in the matrix are been used in a HORIZONTAL way, and every single note is used only three times. In the 2nd movement, the tetrachords in the

matrix are been used in a VERTICAL way (see also the excerpt below). In addition, the matrix is symmetrical with the 4th row as the pivotal axis. That is, line 3 and 5, line 2 and 6, and line 1 and 7 are identical to each other. In addition, the first tetrachords (original tetrachords) are repeated at the end of each row.

Since the two movements follow horizontal and vertical line respectively in the matrix, this composition is called Cross Matrix.
