If you're closing a podcast or making an exit to an 'outbreak' (radio station commercial break) you may want to consider using a ramp jingle.

What is a ramp? In real world terms a ramp helps you to get somewhere and that's exactly what it does in the audio world. A piece of music starts up which you can talk over and use to tell your listeners what's coming up next or in your next episode. Many radio DJs love to talk up to the vocals of a ramp - it sounds really pro - but be careful not to slip into using filler words like, "right here", "only here" or "keep it locked!"

A jingle ramp contains music leading up to sung or spoken vocals which could identify your podcast or radio show name.
