His itemized list of what each class receives helps build anticipation and a deep connection with the project, even in its infancy. A great project with great implementation.
Reverbs come in many shapes and sizes, but a good rule of thumb is to use shorter reverbs like rooms and plates for more upbeat songs, and longer reverbs like halls for slower ballads. Most reverbs and delays can be synced to the tempo of the track, allowing you to dial in just the right amount of decay. Try setting the decay time so the effect fades away just before the next phrase begins.
