So what can we do to avoid inflicting further musical misery on our own customers while they’re patiently sitting on hold? We could just go back to playing a ringing sound, or an intermittent beep just to let people know they’re still connected, but that would be awfully dull. The best compromise is relatively simple electronic music that doesn't have too much going on as the ideal choice for hold music as it requires far less refined sound quality to get a decent rendition down a telephone connection.
By learning the Unique Selling Points of your organisation, we will craft a powerful on hold message script that meets your customer relationship, communication, marketing and business objectives. Your messages are then digitally recorded by our talented voice artists.

You might be thinking, “Great, thanks for the info, I’ll go pick something neutral, like classical, or upbeat, like pop.” Slow your roll—there’s a lot more to hold music than just genre.
“Call center operators who picked up the phone reported feeling less emotionally exhausted when dealing with customers who heard standard pop music.” –Time, “Why Music on Hold Drives You Crazy”
