No. Rock melts when temperature reaches a high enough point. Increasing pressure actually raises the temperature needed to melt rock, so it can actually cause molten rock to solidify.
Igneous rocks-after having the chance to cool down after a melt (metamorphic rocks need pressure as well)
Heat and Pressure
temperature, pressure, and fluid
Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
First magma then there is heat and pressure which makes igneous rock then compaction, deposition, and cementation that makes sedimentary rock then more heat and pressure but not enough heat and pressure to melt it but enough to change it to metamorphic rock! and there you have it it's The Rock Cycle

Metamorphic rock which is exposed to increasing heat and pressure from various sources can eventually melt. If this melt then solidifies, it has become igneous rock.
The main cause for a rock to melt and form magma is constant pressure and heat in the mantel
Heat and Pressure
Decreasing the pressure on rock will allow rock to melt at lower temperature. High pressures will raise the melting point of rock.

No rock would melt because of high pressure. High pressure inhibits phase transformations like solid --> liquid or liquid --> gaseous as you may experience when you use a pressure cooker. It is the elevated temperature that does the trick.
