The filtration is the same for each of the hours so there is no specific progression. If a client is drawn to the music in a particular hour, they can continue to listen to that hour over and over.
There are no requirements for how to listen: it can be via speakers, earbuds, or their over-the-ear headphones.
The volume setting is the same: the first comfortable level. The volume isn't modulated as much in SSP Balance as in SSP Core so we haven't prescribed a Volume Test Track.
Relative to frequency and length, the therapist should help the client to understand what might be the best "dose" and pacing.
There are not the same concerns about over-listening. People may find they can listen to SSP Balance daily or even multiple times a day. They'll need to listen to their body's response and adjust as appropriate.
Clients whose autonomic tendency is toward a dorsal vagal response may find the music activating in an aggravating way. If this is the case, they can shift to SSP Connect: Classical. They may want to keep trying with SSP Balance as it can be a state shifter out of dorsal. Agitation may occur since one must go through sympathetic activation from their dorsal state, but it may also help them to get a foothold in ventral vagal.
One child has called SSP Balance "the magic music"!
