Concert-Diary has been advertising classical concerts since 2000, mainly in the UK, and (unlike some listings websites) allows you to go back and look at historic data. Concerts can be classified under several headings – one of which is “Christmas”, so I thought it would be interesting to look at this century’s Christmas concerts.

Why it pays to perform last
One of the annoying things about TV talent shows is the fact that the winning act very often seems to be the one that performed last. I thought I would check whether this was actually the case, using the Wikipedia data detailing all 15 series of the UK ‘X Factor’.

The value of statistical techniques in historical musicology depends on the quality of the available data. The extent and diversity of these sources is considerable, but it is important to remember that they can only ever illuminate a small proportion of the musical world.
A historical musical dataset can be thought of as a snapshot of part of the entirety of musical activity. Although we may be tempted to extrapolate our conclusions beyond the scope of the data, there are fundamental reasons why such extrapolations can only ever be valid within narrow limits.

Triangulation
Triangulation is a research technique that involves looking at the same thing from two different perspectives. In surveying, it enables positions and distances to be calculated by measuring angles from two locations. In the social sciences, it can increase the reliability of conclusions if they are found by two (or more) different methods. And in statistical historical musicology, looking for the same works or composers in two or more datasets can tell us a lot about the characteristics of the datasets, and about the works’ patterns of survival or dissemination.

Further thoughts on Composers’ Star Signs
Following this previous article, a friend got in touch to thank me for disproving some astrological ‘nonsense’. I replied that I had not disproved anything – I had just failed to find supporting evidence – but it did get me wondering about the nature of the conclusions that can be drawn from this sort of analysis.
Suppose, for the sake of argument, that people born under Aquarius do show a significantly higher propensity to become composers than those born under Virgo. Consider these three possible explanations… Continue reading →
Lies, Damned Lies, and Composers’ Star Signs
On the classical.net website there is a list of 715 composers and their dates of birth. It is straightforward to use this data to identify each composer’s star sign, which produces this interesting chart: Continue reading →
Pick a composer, any composer
Often in statistical analysis we need to select things at random. For example, if it is impractical to work with a complete dataset, the only option might be to use a random sample. The science of statistics tells us how to analyse a sample in order to reach conclusions about the entire dataset, and gives us ways to calculate margins of error based on the size of the sample. But I digress.
So, how might we pick a random composer? Continue reading →
The Size of Symphony Orchestras
The graph below illustrates the size of orchestra required to perform symphonies composed between 1750 and 1920. Each symphony is represented by two dots: the red dots and line represent woodwind instruments; blue relates to brass instruments. Continue reading →
Publication dates of music in the British Library
If you go to the British Library online catalogue, search for music scores published in each year from 1650 to 1920, and plot the number of ‘hits’ by year, the result looks like this. Continue reading →
Women Composers: Sources and Bias
There is a lot of interest at the moment in women composers. Until recently, women were a small minority of the composing population, but in working with large datasets, I encounter a surprisingly large number of female names (although it is often frustratingly difficult to find out any details about them). In the nineteenth century, for example, perhaps 1-2% of published music was written by women.1 Whilst that is an embarrassingly small proportion, it still equates to a substantial body of music by many hundreds of women composers – most of whom have since sunk into obscurity. There are of course many more from the twentieth and twenty-first centuries.2 Continue reading →
