Melting of the bulk of the metamorphic rock, then solidification from cooling, will form an igneous rock.
heat and pressure
Heat and pressure form metamorphic rocks.
Heat and pressure cause granite to change to gneiss.

By melting and then solidifying from melt. Increasing heat and pressure can cause metamorphic rock to enter higher and higher degrees of metamorphism until they may finally reach the point of melting. When this molten material finally cools, it is considered an igneous rock.
Metamorphic rock
Directional pressure and high temperatures are two factors that could cause an igneous rock to metamorphose. Processes that lead to these factors could be tectonic plate movements, depth of burial, or proximity to an intrusive body.
Heat and pressure cause granite to change to gneiss.
The process that can change an igneous rock into a metamorphic rock is called metamorphism. This occurs when the igneous rock is subjected to high temperatures and pressure deep within the Earth's crust. These conditions cause the minerals in the rock to recrystallize and realign, forming a new metamorphic rock with different physical and chemical properties.

Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
No, rock does not melt when it is changing into metamorphic rock. Metamorphic rocks form from pre-existing rocks, such as sedimentary or igneous rocks, through a process called metamorphism. This process involves changes in temperature, pressure, or the presence of fluids, which cause the minerals in the rock to recrystallize without melting.

Metamorphic rock
if rock melts it will form magma, which leads to the formation of igneous rocks
Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form. This rock was compressed into an metamorphic by the tons and tons of pressure causing it to overheat and cause a change which can be chemical or physical.
Directional pressure and high temperatures are two factors that could cause an igneous rock to metamorphose. Processes that lead to these factors could be tectonic plate movements, depth of burial, or proximity to an intrusive body.
The metamorphic or igneous rock would have to be weathered and eroded until it is only particulates. Those particulates must then be forced together as a layer under gravitational pressure. These particulates will then become sedimentary rocks.
