Tamiz in ancient time was divided into prose(iyal), music (isai), drama (n^Atakam). But today very less people even among Tamiz speaking know about the Tamiz isai. Tamiz music has a lot of similarities with carnatic music. There are people who argue that carnatic music came from Tamiz music. The reference to Tamiz music is there in ancient Tamiz literature like SilappadhikAram.
The following list gives the equivalent in Carnatic music

The following are structures and so no specific rAga assigned.
1. thiruk kuRun^thokai
4. thiruth thANdakam
In the above table some of the paNs have same carnatic rAgA equivalent. (like kolli, kolli kauvANam have equivalent as navarOs). There should be some differences. People who have good knowledge on both music systems will be able to explain.
In the first seven thirumuRais (thEvAram as they are collectively called), nineth thirumuRai and some portions of eleventh thirumuRai (kAraikkAl ammaiyAr) the paN for every padhikam is specified and it is supposed to be sung in only that specified paN. There is a paN thiruththANdakam which is found in many of by thirun^Avukkarasar 's thEvArams and they are the oldest usage of that particular paN. So thirun^Avukkarasar is also called thANdaka vEn^dhar.
As vINA is the major music instrument in carnatic music, yAz was the most famous music instrument that gets mentioned in many of the ancient Tamiz literature. It is also a string instrument like vINA. There were a lot of musicians called pANar used to play the songs in the instrument yAz. A lot of saN^gam literature were written with the pANar as main characters.(perumpANARRuppdai, chiRupANARRuppadai etc.). Thiru n^IlakaNta yAzppANar of thiru erukkaththam puliyuur used to play the padhikams of thiru nyAna samban^dhar in yAz. More information on this instrument yAz can be found in "yAzn^Ul" written by swami vibulAnan^dha. Some of the other music instruments that are referred in thirumuRai are vINA (string instrument), kokkarai, kudamuzA (thALa instruments). Some hymns in "kallAdam" describe about these instruments.
All the thEvArams were locked up in a room in the chithambaram temple for some centuries. When the "Shiva pAdha sEkara" "thirumuRai kaNda chOza" emperor rAjarAjan took them out, the paN for many of the padhikams were not known. He asked madhaN^ka chULA maNiyAr, a woman successor came in the yAzpANar family specified the paN for all the padhikams and the padhikams are sung only in that specified paN.
The twelfth thirumuRai periya purANam tells about the making of flute and playing on the flute in AnAya n^AyanAr purANam songs 13, 24-28. kallAdam has reference to lot of music instruments.
