In 2005 – 2006 I developed the quarter-tone charts pictured below (for my Yamaha YSS – 62S soprano saxophone) in order to study and perform traditional Arab and Persian classical music. Since then dozens of professional musicians have used them, including the World Music Ensemble at Berklee College in Boston. The fingerings and exact pitches take some getting used when working them into one’s scale practice, but my charts at least make such study possible. A lot of people ask me for these charts, so I am (once again) putting them up for you all to download and use. Enjoy!
Note: if you are using these charts to play traditional Arabo-Persian music, make sure you remember to use them judiciously. Such quarter-tones are particularly powerful when nuanced and reticent, so use them wisely.
