An online tuner or tuner app can only be used on a device with a good microphone (smartphone, tablet, or newer laptop). If you do not have a device with a good microphone, please purchase the Donner Tuner listed on the "Supplies" page of this website.
You can use an app, online metronome (google the word metronome and one will come up), or the Donner metronome listed on the "Supplies" page of this website.
Disclaimer: These are the apps that we will use in our lessons. You can use any app or physical metronome tuner you want, as long as it gets the job done!
