As an essential component of your marketing and customer service efforts, Message on Hold will reinforce your organization’s message in other mediums. Its effectiveness can be judged by satisfied callers, ready to do business. Often, our clients report that their Message on Hold programs informs their callers about products, services, or promotions that the callers were previously unaware of.
If it is a genre, hold music, it's fair to say, is a troubled one with few hits. It's not really meant to be loved or even listened to — it's meant to communicate something specific: Don't hang up. (Cornell makes this plea specifically at the end of his song.) Silence is believed to be a death knell for phone calls — people will simply think the line is dead and hang up. This is true even on non-hold calls; it's why phone companies transmit something called a "comfort tone" over phone lines, a barely audible synthetic noise that signals a connection is still there.

On average, 5 to 15 seconds of music plays between each message blurb. Keep your audience in mind: musical breaks that are too long are boring, but message blurbs that are long or too detailed can be overwhelming. In most cases, 5 to 15 seconds, between message blurbs that don’t exceed 30 seconds are usually appropriate.
