 ## Dataset Description
 
-- **Homepage:** Scraped from [Mutopia Project](https://www.mutopiaproject.org/) guitar section.
-- **Repository:** I primarily use the implementation created by [Dr. Tristan Behrens](https://www.linkedin.com/in/dr-tristan-behrens-734967a2/) [MMM: Exploring Conditional Multi-Track Music Generation with the Transformer and the Johann Sebastian Bach Chorales Dataset](https://github.com/AI-Guru/MMM-JSB) with a few modifications.
-- **Paper:** I encoded the guitar pieces using the [MMM: Exploring Conditional Multi-Track Music Generation with the Transformer](https://arxiv.org/abs/2008.06048)

 ### Dataset Summary
 
-Mutopia guitar dataset is a dataset consisting of the soloist guitar pieces of the Mutopia Project. I encoded the MIDI files into text tokens using the excelent implementation of Dr. Tristan Beheren of the paper: MMM: Exploring Conditional Multi-Track Music Generation with the Transformer (with a few adaptations).

-The dataset mainly contains guitar music of the western classical composer, such as Sor, Aguado, Carcassi, Giuliani, among other.

 ### Supported Tasks and Leaderboards
 
-Symbolic music generation using Transformers.
+Anyone interested can use the dataset to train a model for symbolic music generation, which consists in treating symbols for music sounds (notes) as text tokens. Then, one can implement a generative model using NLP techniques, such as Transformers.
