+The data in the column `midi` are raw bytes. You may want to use packages like `mido` to analyze them. For example, to view the content of the first MIDI file, you can use a script as follows:
+
+```python
+train_data = dataset['train']  # assuming you already loaded the dataset as described
+
+# Take the first example
+midi_bytes = train_data[0]['midi']  # this is raw bytes
+
+# Load with mido
+midi_file = mido.MidiFile(file=io.BytesIO(midi_bytes))
+
+# Inspect tracks and messages
+for i, track in enumerate(midi_file.tracks):
+    print(f"Track {i}: {track.name}")
+    for msg in track[:10]:  # print first 10 messages
+        print(msg)
+```
 
 ## License Merging
 While most files in IMSLP are stored as public domain or open source, different and sometimes incompatible licensing agreements exacerbate the conflation of individual pieces into a single data collection.
