	<span>The dataset
	</span></h2>

<p>To train a Transformer to tell what type of music is playing, we’ll need some song samples and their musical genres. We’ll use the famous <a href="https://huggingface.co/datasets/marsyas/gtzan" rel="nofollow">GTZAN dataset</a>, which consists of 999 song samples across 10 different genres. The dataset is available on the Hugging Face Hub, so let’s download it to get a sense for it contains:</p>

<p>Notice that we specified a single split to download; that’s because GTZAN doesn’t have a predefined training and test split. We’ll create our own splits for training and evaluation shortly. If we take a look at one of the examples, we can see that we’re provided with a file path, an <code>audio</code> object, and the music genre:</p>
