The intonation of a language can be described as its melody.
I liked this video - https://www.youtube.com/watch?v=Kpdgi6_qeU4
The Video was called "PHO108 - Suprasegmental Features"
[See: PHO108 - Suprasegmental Features] 
[See: The Virtual Linguistics Campus]
Here is there description of their video if you're interested.
:"This E-Lecture provides a phonetic description of the main suprasegmental features: loudness, pitch and length. In addition to these main suprasegmental features, a discussion of secondary articulation as well as co-articulatory effects is appended including as many examples as possible.."
