Acoustic Tuner Alexa Skill
If you play a musical instrument (or sing) it is important to keep in pitch. This skill will play a pitch perfect tone (to the concert A440 standard) for you to tune against your instrument. It can play from the first to the tenth octave. To hold a tone longer, ask it to "repeat". Or you can say another tone to play. If you want to cut it off, say "Alexa stop".
