~ Tarsos at 'Study Day: Tuning and Temperament - Insitute of Musical Research, London'

Tarsos LogoThe 17th of Octobre 2011 Tarsos was presented at the Study Day: Tuning and Temperament which was held at the Institue of Music Research in Londen. The study day was organised by Dan Tidhar. A short description of the aim of the study day:

This is an interdisciplinary study day, bringing together musicologists, harpsichord specialists, and digital music specialists, with the aim of exploring the different angles these fields provide on the subject, and how these can be fruitfully interconnected.

We offer an optional introduction to temperament for non specialists, to equip all potential listeners with the basic concepts and terminology used throughout the day.

~ Tarsos presentation at 'ISMIR 2011'

Tarsos LogoOlmo Cornelis and myself just gave a presentation about Tarsos at the at the 12th International Society for Music Information Retrieval Conference which is held at Miami.

The live demo we gave went well and we got a lot of positive, interesting feedback. The presentation about Tarsos is available here.

It was the first time in the history of ISMIR that there was a session with oral presentations about Non-Western Music. We were pleased to be part of this.

The peer reviewed paper about our work: Tarsos – a Platform to Explore Pitch Scales in Non-Western and Western Music is available from the ISMIR website and embedded below:

Tarsos LogoDuring the the demo session of the IEEE Workshop on Applications of Signal Processing to Audio and Acoustics a demonstration of Tarsos was given. During the demo, the 18th of Octobre 2011 feedback was gathered.

During the conference I met interesting people and their work:

Carnatic Music Analysis: Shadja, Swara Identification and Raga Verification in Alapana using Stochastic Models
Ranjani HG, Arthi S, Sreenivas TV

Simulation of the Violin Section Sound based on the analysis of orchestra performance
Jukka Pätynen, Sakari Tervo, Tapio Lokki

Another interesting paper is Informed Source Separation: Source Coding Meets Source Separation. A demo of this can be found here.

~ Bruikbare software voor muziekanalyse

Op dinsdag vier oktober 2011 werd een les gegeven over bruikbare software voor muziekanalyse. Het doel was om duidelijk te maken welk type onderzoeksvragen van bachelor/masterproeven baat kunnen hebben bij objectieve metingen met software voor klankanalyse. Ook de manier waarop werd besproken: soorten digitale representaties van muziek met voorbeelden van softwaretoepassingen werden behandeld.

Voor de les werden volgende slides gebruikt (ppt, odp):

De behandelde software voor klank als signaal werd al eerder besproken:

  • Sonic Visualizer: As its name suggests Sonic Visualizer contains a lot different visualisations for audio. It can be used for analysis (pitch,beat,chroma,…) with VAMP-plugins. To quote “The aim of Sonic Visualiser is to be the first program you reach for when want to study a musical recording rather than simply listen to it”. It is the swiss army knife of audio analysis.
  • BeatRoot is designed specifically for one goal: beat tracking. It can be used for e.g. comparing tempi of different performances of the same piece or to track tempo deviation within one piece.
  • Tartini is capable to do real-time pitch analysis of sound. You can e.g. play into a microphone with a violin and see the harmonics you produce and adapt you playing style based on visual feedback. It also contains a pitch deviation measuring apparatus to analyse vibrato.
  • Tarsos is software for tone scale analysis. It is useful to extract tone scales from audio. Different tuning systems can be seen, extracted and compared. It also contains the ability to play along with the original song with a tuned midi keyboard .
  • music21 from their website: “music21 is a set of tools for helping scholars and other active listeners answer questions about music quickly and simply. If you’ve ever asked yourself a question like, “I wonder how often Bach does that” or “I wish I knew which band was the first to use these chords in this order,” or “I’ll bet we’d know more about Renaissance counterpoint (or Indian ragas or post-tonal pitch structures or the form of minuets) if I could write a program to automatically write more of them,” then music21 can help you with your work.”

Om aan te duiden welke digitale representaties welke informatie bevatten werd een stuk van Franz Liszt in verschillende formaten gebruikt:
