Filters and Amplifiers.
I particularly enjoy this marketing concept because it draws from sound circuitry principles.
In sound design, amplifiers boost audio signals for driving loudspeakers while filters remove certain frequencies from your signal. Similarly, in your promoting efforts every single aspect of your brand either increases or decreases audience interest.
Your chosen alias, the colors of the background of your website, how you master your tunes, what time and day you post, the medium you perform on..
Every single aspect.
For example, the words you use in a post will either amplify interest in clicking the link to your new work, or filter their interest out. Are you likely to click on links people post that use all caps? “DOWNLOAD MY NEW TUNE!”. Likely not. That is an example of a common filter. Using the title “New Synthy Juke – Free 320 Download” is more likely to amplify participation from your audience instead.
Start noticing what attracts you and repels you from other peoples work.
Look into what might be filtering out interest from your audience, and where you can strengthen your message.
