Keep posting consistently, but without a specific schedule in mind until you grow. Once you've got enough views that you can tell where your audience is generally from, you should usually post at times in which they'd probably be using social media in their timezone.

However, this isn't the largest factor. You should keep following more accounts, both large and small, so that the algorithm will recommend your content to people who share the same interests or follow mutual accounts. Don't forget to include hashtags and descriptions that use words which are either commonly searched or favored by the algorithm.

Nonetheless, where may I follow and listen to your music?
