Can I play in direct sun?
No. If you play in the direct sun or an environment which the instrument is hot to touch, you will surely alter the tuning. If your instrument gets too hot to the touch, it will be fine if not played until it cools down. Also, please refrain from keeping your TerraPan from being locked up in a hot car for extended periods of time, as this is not good for the health of children, animals or TerraPans.
