The Otamatone is an electronic synthesizer built into a tadpole-shaped body about 10.6 inches long. You slide a finger along the stem to change pitch, exactly like a fretless string, and squeeze the cheeks on the head to open the mouth, which adds vibrato and a vocal wah effect. There is no keyboard and nothing to read, so the learning curve is a few minutes rather than months, though playing in tune takes real practice because the stem is continuous rather than stepped. It runs on three AAA batteries and has a low, medium and high pitch switch. Best fit: people who want to make music without lessons, gift lists for teens, and anyone building a video setup around a recognizable sound.
Pros
- No notation or keyboard knowledge needed to start making sound
- Squeeze-the-cheeks vibrato gives it an expressive range most toy instruments lack
- Runs on AAA batteries with no cable or amp required
- Compact enough at about 10.6 inches to travel in a bag
Cons
- The stem is continuous with no frets, so playing in tune takes genuine practice
