In the anime, while Synchro Summoning, the Tuner monster is said to be tuned with the other monsters.
In the anime, many characters have chants for some of their Synchro Monsters, which they recite while Synchro Summoning them.
How to Summon a Synchro Monster
1. During your Main Phase 1 or 2, when the total Level of a Tuner Monster and 1 or more Non-Tuner Monster(s) you control is equal to the Level of a Synchro Monster you want to summon, you can declare that you are performing a Synchro Summon. These Tuner Monster and the non-Tuner Monster(s) are called the Synchro Material Monsters. Redundant monster(s) are irrelevant.
2. In order to Synchro Summon a Synchro Monster from your Extra Deck, you add the level of a Tuner Monster on your field to the level of another face-up monster(s) you control. . That value must equal the level of the Synchro Monster you wish to summon..
A Synchro Summon is another type of Special Summon.
3. After sending the monsters from your side of the field to the Graveyard, you then place the Synchro Monster from your Extra Deck in face-up Attack Position or Defense Position on your side of the field.
