# FürElise: Capturing and Physically Synthesizing Hand Motions of Piano Performance
This hosts the [FürElise](https://for-elise.github.io/) dataset, which contains 10 hours, 153 pieces of piano music performed by 15 elite-level pianists, along with synchronized audio and key pressing events.
# Getting Started
To download the dataset and the related scripts, first run
```
git lfs install
# We skip the raw dataset.zip because it's too large
GIT_LFS_SKIP_SMUDGE=1 git clone [email protected]:datasets/rcwang/for_elise
```
And then download dataset.zip
```
cd for_elise
sh ./download_data.sh
```
# 3D Visualizer
We provide a web-based 3D visualizer of our dataset under `visualizer/` which has the same functionality as the one you see in the [project website](https://for-elise.github.io/). You can run it with the following commands:
```
cd visualizer
python server.py
```
Then you can access the visualizer by visiting `http://127.0.0.1:8080`. You need `flask` and `numpy` to run the visualizer.
For some long pieces, it might take several seconds to initialize the visualizer.
# Dataset structure
The metadata for all 153 pieces can be found in `metadata.json`:
```
[
{
"name": "Concerto in D Minor, BWV 1052: I. Allegro",
"composer": "J.S. Bach",
"piece_id": 0,
"subject_id": 0
},
...
]
```
Motion data for each music piece is stored in a single subdirectory under `dataset/`. The motion data is stored frame by frame with FPS 59.94.
```
