Step 1: Acquire the things you need
• Drumsticks are the first thing you’ll need. A packaged set of sticks with multiple pairs can be purchased for $10 - $30.
• Drum pad. Once you have something to drum with, you’ll need something to drum on. To avoid annoying your roommates or family, a drum pad is the best bet. Drum pads are relatively quiet and typical pad is around $20, although you can find them for north of $100 if you want one with a metronome.
• Metronome (recommended). Drumming is all about keeping a steady tempo. A metronome is a device that produces metrical clicks at whatever tempo you choose. This allows you to have more structure when you practice. Whether you think you have rhythm or not, a metronome is a must. As previously stated, you can buy drum pads with metronomes built-in. This would be a good investment. A standalone metronome can cost anywhere between $10 and $100.
Note: Make sure you buy a metronome that you can either hook up to a speaker or is loud enough to hear over your drum.
• Rudiment Book (recommended). If you don’t know how to read music, it’s ok. Learning note values is not difficult. If you can do basic addition you can learn note values. This will help you in learning and practicing different rudiments, which are fundamental to drumming. There are tons of different books out there, but they all have different variations of largely the same exercises. Go online (I list a website at the end of this step) and find a book with a high user rating, and you should be set. If you search, you can also find tons of exercises online for free.
• Lessons (recommended). Unless you’re a prodigy, taking lessons from an experienced drummer will help you learn and hone your skills much faster than you would if were to practice on your own. There are also many video lessons online (sometimes for free) that are a viable alternative, but make no mistake that a video lesson is no replacement for a weekly one-on-one lesson.
• Drum set. Once you learn the basics and have determined that drumming is something you'd like to continue with, a drum set is the next logical purchase. You should be confident that you can and should move to the next step before you make this purchase. It is important to note that this is not something you would want to go and purchase right away. You wouldn't buy an expensive car if you didn't know how to drive, so you shouldn't buy a drum set unless you know what you're confident in your fundamental drumming skills. You need to learn the basics and have them down long before you should consider making this purchase. You could literally spend tens of thousands of dollars on a drum set if you wanted to, but unless you’re a professional drummer a beginner or intermediate set for between $400 and $800 will do the job.
Note: In my videos on this instructable I use an electronic drum set. Electronic sets are great if you live in an apartment or somewhere you can't make a lot of noise.
Note: Musician's Friend is a great website that sells practically anything music related that you could ever want.
