Portable electronic tuners are small enough to fit in most instrument cases and provide a reliable way of tuning instruments to sound perfect.  The NS Micro Violin Tuner by D'Addario is the first precision tuner designed specifically for violin & viola. It is not only perfect for tuning, but it can be used as an effective practice tool for referencing and improving intonation while playing.  We truly love this tuner and think it's a terrific way to help a beginner through the difficult beginning stages of playing and tuning their instrument.
