Sir Paul McCartney joined the team at Skype to create 'audio emojis' to celebrate Valentine's Day.

McCartney's musical compositions are coupled with moving emoji designs that last about five seconds. The emojis can be sent to your family and friends through the messaging platform for free.

Skype's Mojis were launched last September. They are different from emoticons in that they can feature sound and video. The emojis took about a week to produce, and include emotions such as love, blushing, flirting, and more.

McCartney used instruments which include the Moog synthesizer, harpsichord and electric guitar, as well as his voice.

The latest Skype app is available on Windows, Mac, Android, or iOS. Click for more on Skype and their "Love Mojis"
