Registration of longitudinal data by means of musical notation

There is a lack of good registration methods for complex longitudinal data. Cumulating longitudinal data into cross-sections, even repeated ones, in order to allow for statistical analysis means considerable distortion of data; if they interact with each other, this is not possible to observe directly and the time factor is not taken into account to its full value, if at all. In this context, music may be defined as a complicated development in the course of time. Music is usually represented by musical notation which, if not ideal, means that we already possess a high precision registration method for complicated temporal developments. Musical notation used for registration of other longitudinal variables than musical ones allows for a multitude of qualitative variables being taken into account simultaneously and a high precision regarding the time factor. It should be no more difficult to analyse statistically a longitudinal pattern than a surface pattern.
