This special sound makes the water harp shine in the film soundtrack, which is used in Alien, Crouching Tiger, Hidden Dragon and The Matrix. Brass scales with different lengths and diameters are installed around the cylindrical handle of the water harp, and there is also a stainless steel resonance bowl filled with water.
Tap with a drumstick or play with a bow, and the water in the bowl will resonate with the bowl and make various sounds. When playing, lifting the water harp and rotating the water on the partition will distort the timbre and give off a strange front echo.
The melody, rhythm and pitch of music will have a certain impact on people's emotions, so let's look at the musical elements first.
Modern music is mainly divided into major and minor, and the structure of major is "full tone, full tone, semitone, full tone, full tone and semitone". For example, Do, re, mi, Fa, Sol, La and si are called c major. The structure of "diatonic, semitone, diatonic, diatonic, diatonic, diatonic" is called natural minor.
Therefore, compared with major, minor has shorter intervals (the distance between pitches) and higher tension, which is easy to convey negative emotions, while the music of horror movies is often written in minor.
