Zelda Music box combination lock

Projects General Guidance
1

I'm currently in the process of making a combination lock box that plays ocarina sounds from the N64 Legend of Zelda series.

The idea is that there will be an on/off switch and 5 buttons for the ocarina sounds. A programmed song will acted as the combination and play a tune when correct. Which will release an electric lever.

I need some help figuring out the layout and design.

Using:
Arduino Uno R3
DC 4.5V Actuator

A user will press some combination of the 5 buttons (within a certain time limit) and, if the combination is correct, a specific music file will play and the lock will open ?
