i want it so when i turn the master switch on all the lights turn on and disable all the normal switches wth the lights.
Maybe I'm not following you but it sounds like a code violation. Each room needs to have a light switch in the room it serves. You can put additional switches wherever you want but I don't believe you're allowed to bypass the switch to the room it serves.

Each room has a single pole with its coresponding luminare. I want to put a master switch in the master bedroom to bypass the switch in the other three rooms and turn the lights on.

Even if the lights are all on the same circuit you can't wire one switch to turn them all on and still have the lights be separately controlled by the room switches without some sort of relay control box. Once you wire the lights in parallel for the master the room switches will also act as master switches to the others on as well.
You can have a master to turn them all off and the individual switches turn them off/on when the master is on.

Not true. Switch locations are not referenced by the code. A bedroom switch could be anywhere. Not too practical or sensible but possible.

To do do what you want
Will require extra wiring
And probably changing
Some of the switch's.
All possible but not easy.
Use three way set ups ?
Or Lutron systems.

I want to do something like this. Is this possible though? I do have a bit of extra room in the coduits to fit extra wires.
You'll need an extra wire from the master room to each bedroom. This wire will come off the load side of a single pole single throw switch. In each room, it will terminate on a brass screw of a three way switch. The other brass screw of each three way switch will get line voltage. The black screw of each three way switch will go to the light in that room.
When the master is closed, or turned on, the light in each room can't be turned off. When the master is open, each room works as any normal house.
This is a very odd request BTW. Horticulture?
I'll post a crude line diagram if interested.

Another way. Easier to do with a single relay if all three rooms are on the same circuit. The relay will require three normally closed contacts and one normally open and must be rated for the load.
You will have to mount a relay panel somewhere. The hot from your power panel will enter this relay panel and feed the top side of all four contacts of the relay. You will also need a neutral for the coil of the relay. From the bottom side of each NC contact a hot wire will feed the light switch in each of the three rooms (line side).
The wire from the NO contact will then feed all three lights. It must be terminated behind both the NC and room switch (load side of the switch). It will need to parallel all three switches. You will then mount your master switch wherever you wish. You will need a switch leg from the relay panel to your master switch.
Assuming you terminated everything in the correct place, this is the operation: With the master switch off, power is available to each room switch as usual. When you close the master switch, it will energize the relay coil. The relay contacts will all then change state. The now open NC contacts will disconnect power to each room switch. The now closed NO contact will send power to all three lights. The room switches will have no effect when your master switch is in the on position.
Or you could just teach the kids to get up on time.

Arrow, I find our two contrasting posts very interesting. I am primarily an industrial control man, so I never considered a three way switch. I find it very cool.

Once you connect all the lights together for the master to turn them on any one of the switches will turn them all on also. The hots still remain connected to each other when off.
The only way to do is with relay system so the hots stay separated or with a 3 pole master switch which will also keep the hots separate when off.

Can i see that line diagram? I think joed is right if you terminate all of the load side together you cant turn on each light with its coresponding switch

That appears to work using the three ways switches in the rooms. If the light is off the master will turn it on via the second traveller screw on the three way. If someone tries to turn off the light via the room switch when the master was on, they can't because one feed is always hot and the other is hot via the master switch.
Nice thinking. I never thought of that option.
This all relies on all the light being on the same circuit. If any of the rooms are on separate circuits they need to altered to be on the same circuit.
