The actual planning will depend on the age of your kid; toddlers and pre-schoolers will enjoy home-made instruments, tweenies and teens can go with disco parties or their favourite pop star's music.
You can also focus on music from different countries.
Invitations: Invitations can range from normal card invitations with images of music notes or instruments, to invitations made from CD's, sheet music (and no, you don't have to use your music books, just make copies or search online for images to download) or drums made from small empty canisters with the invitations inside.
Birthday Cake: Birthday cakes can be in the form of drums, boom boxes, gramophone players, radios, or music instruments like guitars and pianos.
You can use modelling paste to make musicians and also place it on the cakes or next to the cakes.
Make party snacks that look like music notes or music instruments.
Use cardboard templates to cut out shapes from slices of bread, pizza dough or cookie dough and add different toppings.
Decorate Marie Biscuits or any other suitable biscuits to look like CD's.
Turn old vinyl records into bowls to hold candy and crisps.
Decorations: This will once again depend on the specific music theme you choose.
Here's a chance to use all those old CD's by attaching them to foil swirls; simply cut some coloured foil pie plates in a spiral, attach the CD's with glue and hang from the roof.
Music notes cut from brightly coloured construction paper can be mounted on the walls or hung from the roof as well.
It also adds a festive touch to the table decorations.
Buy or let print big posters of popular musicians or favourite singers and decorate the walls with it.
Party Games and Activities: Young kids will enjoy games like musical chairs or musical glasses - pick some glass bottles that make a good tone when you strike them.
Six will do.
Fill the first bottle with water, the second one with less water, and keep going until you get to the last one.
By this time, you should just be able to fill it with about an inch or so of water.
When you tap each bottle using a spoon or stick, you will notice that they produce a different tone and sound.
Glasses can be filled in the same way, wet a finger and rub it around the rim of each glass.
Each glass will make it's own sound depending on the amount of water in it.
Drums can be made from brightly painted empty coffee cans; toddlers will love pots and pans with a wooden spoon, fill balloons with a small amount of sugar before tying, make shakers and other noisemakers by filling empty plastic bottles and empty tins with beans or rice.
Karaoke, name the song/tune and musical trivia are all games that will be enjoyed by older kids.
Consider giving dance lessons to the kids especially if your party theme centers around music from other cultures or earlier eras.
If you do not know all the dance steps yourself, ask friends or family members if they can do it, or if your budget allows it, hire a professional dancer from a dance studio.
If all else fail, buy a DVD with the appropriate dance steps and let the kids have a lot of fun following the basic steps.
Party Favours: If you let the kids make their own music instruments as part of the party activities, they can take it home with them.
Older kids can be presented with a CD with music from the era you chose - you can easily choose songs before the party and burn CD's on your computer.
if you have a graphics program and printer, design a CD cover with the date and time of the party as well as the birthday kid's name on it; the party guests will have good memories of the party every time they listen to the music.
Children love to dress up for a party and a music themed party theme will give them the opportunity to step into another era as they can become rock 'n rollers, pop stars, drummers or dancers for the duration of the party and who knows, one or two of them may just discover their future careers while enjoying the music at your child's birthday party.
