Sound of the 2 note tuning of my upright piano. These are the "A" and the "D" (the lower fifth). You will first hear the 1st string of "A" (right), then with the 2nd (wrong) that I will tune, then the last will be tuned to finish. The "la" is therefore correct. Ditto for the "re". You will hear the sound of the tuning key for the 2 notes. Non-stop recording, without faking. UCS Category: MUSCInst. Duration: 02:18.
