Editor's note - With the holidays approaching, we're getting lots of questions asking for assistance in finding the right theremin to give as a gift. To help, we've updated our buyer's guide for with fresh considerations for buying a theremin. As always, if you still have questions, please post comments below or post in our forums.
Here at Theremin World, readers often ask "which theremin should I buy?" We've created this handy guide to help you make your decision. When deciding which theremin to purchase, here are 8 important considerations.
Hands down, the first question most people consider is budget. Theremins come in a range of budgets, but the old rule "you get what you pay for" tends to apply.
As with most musical instruments, the more you spend on a theremin, the (generally) higher quality the instrument will be. You can get a fun pitch-only novelty theremin starting around $25, though it won't really be suitable for making music.
You can get a decent starter theremin that is suitable for playing simple melodies for around $120 if you're willing to build a kit. There are a few more durable and professional options in the $250-$500 range (Burns B3, B3 Deluxe, Moog Theremini, Moog Etherwave). Spend a lot more, and you can get a true professional model like the now discontinued Moog Etherwave Pro Theremin or the Tvox tour. Break the bank, and you can even buy a rare vintage RCA Theremin circa 1929!
For most beginners who are serious about learning to play music on a theremin, we recommend the Burns B3 or Moog Etherwave models as a great starting point.
Do You Want To Make Music Or Just Sound Effects?
Consider what you want to do with your theremin. Do you aspire to play classical music? Or are you just looking for something to make spooky sound effects? Or are you looking for a little of both?
Most single-pitch theremins and optical theremins available are best suited for simple noisemaking and not much else. These can still be a lot of fun, but don't expect to become the next Clara Rockmore with one of these.
With a single pitch theremin, you cannot control volume between notes, which tends to be important when playing melodies. For that, you'd need an external control such as a volume control.
Two-antenna theremins, on the other hand, allow you to control both the pitch and volume of each note. It takes a lot of practice to get both of your hands working together, but once you get the hang of it, you'll really enjoy how much control you can have over each note.
If you're looking for a little bit of both, the Moog Theremini Theremin might be right up your alley. Featuring a digital synthesizer engine with built-in effects, it can produce a vast array of sounds from traditional theremin timbres to space-age oddities.
If you want to make music on a theremin, look for one with great pitch linearity. Better linearity means the notes are spaced more evenly apart across the theremin's pitch range. No theremin is perfectly linear, but generally the more expensive models tend to have better linearity and are thus a bit easier to play.
Kit or Pre-Built?
If you're considering a kit theremin, it's important to have at least a basic understanding of electronics and a little previous experience with building electronics kits. If you can follow directions closely and you are comfortable with a soldering iron, you can build any kit out there. Kits are also a great way to save a little money on a decent quality theremin. Even if you're not familiar with soldering, you might be able to find a friend or family member to help you build the kit.
One great kit option is the Moog Etherwave Standard theremin kit. This is a great sounding two antenna theremin with decent linearity, and best of all, most of the soldering and tuning is already done for you by Moog engineers! You simply wire up the controls on the front panel to the main board and finish the cabinet to your liking.
For the more adventurous, the PAIA Theremax kit requires much more soldering.
Timbre and Timbre Control
You can do a lot with effects pedals, but it always helps to have some basic control over the sound generated by the theremin. Do you prefer a harsher sawtooth wave, or a more flute-like sine or square wave output? Be sure to listen to sound samples of a theremin before you purchase one to see if you like the overall tone.
Virtually all commercially theremins these days are easily portable with removable antennas. The old RCA theremins, Big Briar series 91 or Ethervox models came in large wooden cabinets that looked amazing, but were fairly heavy. If you travel with your theremin a lot, consider getting a padded gig bag to protect it.
This may seem minor to some, but consider whether or not you like how the theremin looks. Are you looking for a more classic shape like the RCA lecturn cases, something more utilitarian like the Moog Etherwave, or something fancy like the Wavefront Travel Case theremin?
We hope this guide has been helpful! If you have other tips to help or questions about which theremin might be best for you, please feel free to post comments or inquire in our forums.
