DECODE LYRICS CODE
The code below visualises song lyrics or poetry as suggested by Colin Morris. Pop Music is Stuck on Repeat | Colin Morris | TEDxPenn
DECODE LYRICS HOW TO
The next section shows how to implement this approach with ggplot, scraping pop song lyrics from the website. Towards the end of the song, we see the bridge, which is like a little snowflake within the diagram. After that we see diagonal lines appearing that represent the repetitive use of the song title. The first 30 words are the opening verse, which shows little repetition, other than stop words such as and the pronoun I. The diagram below visualises the lyrics of one of the most famous pop songs ever, Waterloo by Abba. As a result, the bridge is in most songs a unique pattern with self-similarity. Many songs have a bridge that contrasts with the rest of the song. A verse is not very repetitive besides some stop words. The verses are the gutters with only diagonal lines. The snowflake diagrams are a visual language to decode lyrics. Self-similarity matrix for Mary had a Little Lamb by Thomas Edison. It shows where the words “Mary”, “lamb” and “was” are repeated once. The similarity matrix below visualises the two first sentences of the famous nursery rhyme. And everywhere that Mary went, the lamb was sure to go. Mary had a little lamb, whose fleece was white as snow. Let's demonstrate this with the first words ever recorded by Thomas Edison in 1877. The more of these patterns we see, the more repetitive a song is. Patterns away from the diagonal represent two different points in time that have the same words. The timeline of the song thus runs along the diagonal from top left to bottom right. By definition, the diagonal of every similarity matrix is filled. For every point in the song where the row name equals the column name, shows a dot.
In this method, the individual words of the song are the names of the columns and the names of the rows in a matrix. Morris decided to use a self-similarity matrix, which biologists use to visualise DNA sequences, to decode lyrics. Visualisation of the lyrics of Daft Punk's 'Around the World' and Queen's 'Bohemian Rhapsody'. As a result, the more points in the graph, the more often the composer repeated a word The TedX presentation (see below) by Colin Morris shows how he visualises the repetitiveness of song lyrics with what he calls the Songsim algorithm. Bohemian Rhapsody by Queen has some of the least repetitive lyrics in popular music. The most repetitive song is Around the World by Daft Punk, which should not be a surprise since the artist repeats the same phrase 144 times. Colin demonstrated that lyrics are becoming more repetitive since the early days of pop music. This article shows how to decode lyrics from pop songs and visualise them using the Songsim method to analyse their metre.ĭecode Lyrics using the Songsim algorithmĭata visualiser, pop music appreciator and machine learner Colin Morris has extensively analysed the repetitiveness of song lyrics. Poets structure syllables and repeat words to create pleasing sounding prose. Even the lyrics have a mathematical structure.
Numbers can also represent the rhythm of the music. Ancient Greek mathematician Pythagoras was the first to describe the logic of the scales that form melody and harmony. Music is an inherently mathematical form of art.
