There is more than one definition of the saturation ofcolour. In 2008, the author proposed a new formula for the saturation and in this presentation the experimental verification is shown by means of the Japanese Colour System PCCS, The distances in the lines of equal saturation have three maxima and three minima. A connection to neurology and to the colour sensation is possible. Making a new colour space with the saturation, the LSh-colour space, which is much more symmetrically than the LCh-colour space. This is of interest for calculating colour differences. 展开更多

Excavation to creativity is one of important means in the teaching process. Comprehensive musicianship course is an experimental teaching method, but also a teaching art form in the music education system. Many achievements have been made to comprehensive musicianship course since the experimental teaching was established in China. The influence scope of comprehensive musicianship course is constantly expanded in the field of social music teaching, and simultaneously its influencing power is also rising. However, it should be implemented in the process of teaching according to the actual circumstances of the primary and secondary school students in China. In the teaching of comprehensive musicianship course, vocal music performance is applied as the main carrier in form and proceeds very rhythmically in the process of the whole time, and also thoughts and emotions are fully reflected by body languages. It starts from the comprehensive learning, and then is gradually promoted between non-major courses in institutions of higher learning and the music teaching in primary/secondary schools, so that a good teaching effect has been obtained. In comprehensive musicianship course, high importance is attached to the improvement of students' creativity and innovation ability. In this paper, the enlightenment from comprehensive musicianship course on China' s vocal music performance teaching is mainly analyzed. 展开更多
