First let’s make sure we know what these devices are. A metronome is a small machine that makes a clicking sound to help you keep tempo, and a tuner tells you if you are sharp, flat or in tune when you play a note. In the world of music we have tuners, metronomes and combos of both. Some are big, some are small, some sit on your stand while others attach to the bell. What I’m trying to say is, there is a huge variety of machines out there, which is why here I will focus on my favorites and those that have proven to be popular within the music community. The title of each device will take you to amazon.com for purchase and the price is listed under each description. If you’re on a tight budget I will give you a great recommendation for an all-in-one tool for under $5.
