Everyone learned all the parts to the piece and we completed our recording. We didn't play the entire song, but instead went through each section only once. For the "these open doors" section, the rhythm of the chords were very confusing, so I decided to go with the same rhythm I had for the previous section.
In our final recording, the piano and the percussions sound as good as the original. The singers also did an excellent job, but I feel a microphone for the singers would have made our performance even better.
The piano notes and chords were very easy so I did not have to put in too much effort to learn my part for the performance. The main effort from my side was to be a good accompanist. Since the piano starts off the song, I had to make sure that I played the opening bars well and set a good tempo for the others, and I think I did a reasonably good job.
