GitLab now enforces expiry dates on tokens that originally had no set expiration date. Those tokens were given an expiration date of one year later. Please review your personal access tokens, project access tokens, and group access tokens to ensure you are aware of upcoming expirations. Administrators of GitLab can find more information on how to identify and mitigate interruption in our documentation.
This dataset contains multimodal recordings of eight professional violinists performing an excerpt from a standard pedagogic repertoire: Kreutzer's Study No. 2 in C major.
This dataset is reported in the following paper:
Álvaro Sarasúa, Baptiste Caramiaux, Atau Tanaka, and Miguel Ortiz (2017). Datasets for the Analysis of Expressive Musical Gestures. In Proceedings of the 4th International Conference on Movement Computing, London, UK, June 2017 (MOCO'17).
Description
Each subject played the excerpt 10 times using each of the following 5 bowing techniques: detache, legato, spiccato, staccato, and martele.
After the 50 trials were performed, each violinist was asked to play the excerpt with 3 bowing techniques detache, legato, and spiccato, 10 times each, this time varying the dynamic from pianissimo to fortissimo. Finally, each violinist played the excerpt with the same 3 bowing techniques 10 times each, but now varying the speed from slow to fast.
We captured the violinists' gestures with the Myo consumer device to acquire 8 channels of electromyography (EMG) data in a circular formation around the right forearm of each participant, and IMU data consisting of 3-axis accelerometer, 3-axis gyroscope and the MYO's calculated position data which provides Euler angles for pitch, yaw and roll as well as Unit quaternions.
We aimed to keep consistent positioning for all participants by centering the Myo's electrode 4 (logo) over the Extensor Digitorum muscle.
It is important to note that while the centering does give a good reference for examination of muscle activity across users, the specific placement of each EMG electrode is defined by the MYO's form factor and its relationship to varying arm sizes.
