 - You can **retrieve music using any text input (in any language) or an image** (`.png`, `.jpg`).  
 - When using an image, **BLIP** generates a caption, which is then used for retrieval.  
 - Since CLaMP 3's training data includes **rich visual descriptions of musical scenes**, it can **match images to semantically relevant music**.
+- For simplicity, this demo retrieves music based on **metadata (text descriptions)** rather than directly searching sheet music, MIDI, or audio files.
 
 ### ⚠️ **Limitations**
 - This demo retrieves music **only from the WikiMT-X benchmark (1,000 pieces)**.
