Music texture can be said to be a horizontal and vertical design form, and you can understand it as a three-dimensional scheme. Regardless of the connection with the theme of music, graphically, we can look at it like this: 1. Monolinear melody, loose motivation may be followed by intensive changes. For example, the first question is a simple octave, which goes from high to low. One answer is followed by one that is looser or denser than the former, from low to high, or linear. 2. Multi-voice melody (or polyphony), except that the above-mentioned single-linear melody is an independent part, in the vertical direction, it adopts the upper and lower parts to be tight (or vice versa), and the upper part is complicated and the lower part is simple (or vice versa). In fact, all of the above are in the category of harmony composition. However, as beginners, it is of great help for us to know this earlier for our personal simple music creation.
