Reading a scanned book

I have recently been working on extracting data on women composers from the various sources listed in this previous article. The first source on that list is a scanned copy of a French translation of a book – Les femmes compositeurs de musique – compiled in 1910 by Otto Ebel. It is available at here. Although I’ve not had great success in the past in extracting usable data from scanned books, this appears to be a reasonably tidy scan of Ebel, which looks like a useful source on women composers, so I thought I would give it a go.

Surveyor 2Triangulation 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

Aquarius symbol 3Virgo symbol 3Following 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 →

Encyclopedia of Women Composers

I have just taken delivery of a good ex-library copy of the weighty two-volume ‘International Encyclopedia of Women Composers’ by Aaron I Cohen,1 which will be useful for some research I am doing (as well as for writing some materials to accompany a series of concerts by the excellent Bristol Ensemble next year). The encyclopedia weights about 3½kg, has almost 1,200 pages, and lists 6,196 women composers spanning all continents and over four millennia. Each entry includes brief biographical details, lists of works, and references for further reading. 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 →

British Composers as seen by Hofmeister

The gentleman pictured to the right is Welsh composer Henry Brinley Richards.1 Although he is little-known today, his piano nocturne ‘Marie’ Opus.60 was the most published British musical work in Germany in the nineteenth century. German music lovers could purchase ‘Marie’ in its original form or in various arrangements in an impressive 34 separate publications from 27 different publishers between 1861 and 1877.2

That conclusion comes from an analysis of Hofmeister’s Monatsberichte – a monthly listing of music publications appearing in the German market, compiled by Leipzig music publisher Friedrich Hofmeister from 1829 onwards. The Monatsberichte up to the end of the nineteenth century are available as an online database, listing about a third of a million publications from over 36,000 composers. This article is about the British composers and their works that appear in Hofmeister’s listings. Continue reading →

The Semantic Web vs Tidy Data

I have recently been trying to collect data from the Listening Experience Database (LED) in order to put together a proposal for a conference paper. The LED is a nicely constructed database using linked open data and a structure based on something called the ‘Semantic Web’. Rather than traditional databases that have a hierarchical ‘tree’ structure, the Semantic Web concept is a true ‘network’, where anything can be linked to anything else. The LED, for example, includes links to data on a number of other databases. Have a look at the LED and follow a few links and you will see what this means – a very rich and flexible means of linking data together. Continue reading →
