+Sure, here's an example of a FastAPI endpoint that adds music and artist to the database using SQLAlchemy models and Pydantic schemas:
+
+```python
+from typing import List
+from fastapi import APIRouter, Depends
+from sqlalchemy.orm import Session
+from database import get_db
+from models import Music, Artist
+from schemas import MusicCreate, ArtistCreate
+
+from app.api.models.music_model import *
+from app.api.schemas.music_schema import *
+router = APIRouter()
+
+# SQLAlchemy models
+
+@router.post("/music", response_model=List[MusicCreate])
+def create_music(musics: List[MusicCreate], artists: List[ArtistCreate], db: Session = Depends(get_db)):
+    db_artists = [Artist(name=artist.name) for artist in artists]
+    db.add_all(db_artists)
+    db.commit()
+    db.refresh(db_artists)
+
+    db_musics = [Music(title=music.title, artist_id=db_artists[music.artist_id - 1].id) for music in musics]
+    db.add_all(db_musics)
+    db.commit()
+    db.refresh(db_musics)
+
+    return [MusicCreate(title=music.title, artist_id=music.artist_id) for music in db_musics]
+```
+
+Here's a breakdown of the code:
+
+1. We import the necessary modules and dependencies.
+2. We define the `Music` and `Artist` SQLAlchemy models with a one-to-many relationship.
+3. We define the `MusicCreate` and `ArtistCreate` Pydantic schemas for data validation and serialization.
+4. We create a FastAPI router with a `POST` endpoint at `/music`.
+5. The `create_music` function takes two lists of `MusicCreate` and `ArtistCreate` objects, as well as a database session (`db`).
+6. We create `Artist` objects from the `ArtistCreate` objects and add them to the database.
+7. We create `Music` objects from the `MusicCreate` objects, associating them with the appropriate `Artist` objects based on the `artist_id`.
+8. We add the `Music` objects to the database and commit the changes.
+9. We return a list of `MusicCreate` objects representing the newly created music entries.
+
+To use this endpoint, you would send a POST request to `/music` with a JSON payload containing lists of `MusicCreate` and `ArtistCreate` objects, for example:
+
+```json
+{
+  "musics": [
+    {
+      "title": "Song 1",
+      "artist_id": 1
+    },
+    {
+      "title": "Song 2",
+      "artist_id": 2
+    }
+  ],
+  "artists": [
+    {
+      "name": "Artist 1"
+    },
+    {
+      "name": "Artist 2"
+    }
+  ]
+}
+```
+
+This would create two new artists and two new music entries associated with those artists in the database.
