To promote a song well, you need a performant instagram trailer. On Instagram and on social channels in general, it’s important to be personal. At the same time, however, you also want to present a song.
Simply posting a clip from a music video, a visualizer or a picture with music behind it, presents the song as well, but is clearly too impersonal.
This trailer should therefore be supplemented by a personal announcement. For example, you could say „Hey guys, my new song is out now. I hope you like it, be sure to tell me what you think, you can find the link in my bio.“
Some things must be absolutely preserved in this announcement. These include a time limit („now“) and a call-to-action, which means telling viewers exactly what to do („listen“). In combination, this results in, for example, a „Listen now“. Of course, this is a very stripped down version and you can embellish this significantly.
