Now available as a home-printable wall-chart and book of scales, Roedy Black’s Guitar & Keyboard Scales Poster is a 63-page PDF consisting mainly of images. It contains two sizes of the Guitar & Keyboard Scales Poster. Size “A” (Regular Size) is 19" (49 cm) wide x 27" (68 cm) high. Size “B” (Megasize) is 29" (73 cm) wide x 40" (102 cm) high. You can view these two images on your screen at these large sizes. You can also print out the full Guitar & Keyboard Scales Poster in sections on ordinary 8 ½" by 11" paper, then three-hole punch the pages. Then you can put the pages in a small binder and use it as a book of scales. Each page has a “mini-map” at the top, showing you its poster location, much like the pages of a map book or road atlas. Alternatively (or in addition), you can print out the entire Guitar & Keyboard Scales Poster in sections on 8 ½" by 11" paper and trim off the white space around the four edges of each image on each page, using scissors or a straight-edge and paper cutter (similar to a box cutter, but smaller and lighter). You can then assemble the sections into a large wall chart (you have two sizes to choose from). A wall chart gives you access to the scales in all keys at a glance. This has some distinct advantages: You can keep both hands on your guitar or keyboard while learning scales. You don’t have to stop to flip through pages. This makes scale-learning faster and easier. By seeing all the scales logically arranged, key by key, you’ll find it a lot easier to get the “big picture,” to recognize and understand musical relationships. This PDF also contains Roedy Black’s Chord Progression Chart.
