Why use a tuner?
Tuning your instrument is an essential part of playing music. Tuning allows one to produce beautiful sounds on an instrument, as well as play harmonious musical phrases & play in unison with other musicians. You’ll also need to tune your instrument if you want to practice alone, for example, with playbacks or backing tracks.
Learning to tune your instrument is an important part of learning to play. It might be difficult the first few times, but don’t worry, it’ll get easier with practice & soon it’ll come automatically.
Guitars, bass guitars, violons, & ukuleles have a tendency to go out of tune regularly between two sessions or even while you’re playing. Because these instruments are usually made of wood, they can be sensitive to temperature changes, humidity, etc. On top of that, the strings themselves are subject to these same changes as well as wear. Make sure you take the time to tune your instrument properly before using it.
