In this lesson, we go in depth on the uses of a tuner. Metcalf believes strongly that when we practice slowly with the drone of a single pitch, we can effectively train both our ear and our left hand. Tuners, as she explains, are especially crucial when dealing with music that does not incorporate many open strings in the key-signature (such as E-flat major) as we do not have the reference points that we do with an "open" key such as G major.
In this lesson, we go in depth on the uses of a metronome. Step one to using a metronome is often difficult for people, and that is: how to actually stay with the metronome! Metcalf explains practice techniques and ways in which we can train our body and brain to understand the beat and how it relates to the physical motions we must make. As Metcalf notes, "The metronome is never wrong!"
