Seeing the notes laid out in a circle will help you unlock an understanding of how major and natural minor scales are organized, and also how they are related to each other.&nbsp;<br><\/p>\n\n\n\n<p>So how do we first acquaint ourselves with the circle of fifths? Before we even look at that circle, take a look at your keyboard. Start at the lowest C (the farthest on to the left) and go up in fifths. Play the starred notes:<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"742\" height=\"86\" src=\"https:\/\/online.berklee.edu\/takenote\/wp-content\/uploads\/2023\/02\/01Full-Keyboard-Circle-of-5ths.png\" alt=\"\" class=\"wp-image-19044\"\/><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>Note what happens: we end up back on C. In the process, we have touched all 12 possible notes: C, C\u266f, D, D\u266f, E, F, F\u266f, G, G\u266f, A, A\u266f, and B. Let\u2019s see if we can express this in a simple way. First, a quick review and an exercise to point us in the right direction.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Circle of Fifths &amp; Key Signatures | Music for Beginners | Berklee Online | Joe Mulholland\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/G8Sd70RpQ0w?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>You may already know that notes can have more than one name. For example, C\u266f is the same as D\u266d, and A\u266f is the same is B\u266d. Two notes spelled differently are called <strong>enharmonics<\/strong>. It is a term you will hear often at Berklee and in the professional music world.<\/p>\n\n\n\n<p>Take a look at the full keyboard of 5ths. Then, write down the descending notes from the highest C. Name the black keys using only flat names this time.<\/p>\n\n\n\n<p><em><strong><a href=\"https:\/\/online.berklee.edu\/music-theory-harmony-and-ear-training?campaign_id=7010Z000001ZkQgQAK&amp;pid=&amp;utm_source=takenote&amp;utm_medium=blog&amp;utm_campaign=bol-gen-takenote-article-link-circle-of-fifths\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">STUDY MUSIC THEORY ONLINE WITH BERKLEE<\/a><\/strong><\/em><\/p>\n\n\n\n<p>When we do this, we discover that, as we go up in 5ths from C, we get scales with more and more sharps. The reverse is true as we go down from C: we get scales\u2014and key signatures\u2014with more and more flats.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"718\" height=\"236\" src=\"https:\/\/online.berklee.edu\/takenote\/wp-content\/uploads\/2023\/02\/02Circle-5ths-Keyboard-2.png\" alt=\"Illustration: As we go up in 5ths from C, we get scales with more and more sharps.

Memorize the key signatures for each scale.&nbsp;<br><\/p>\n\n\n\n<p>As mentioned in the video, we can continue with the scales with six sharps (F\u266f major) and seven sharps (C\u266f major). Notice that there is a pattern: each time we go up a Perfect 5th (or P5) and build a major scale, one new sharp needs to be added. And that new sharp always falls on scale degree 7 (the leading tone) of the scale, which is a half-step below the tonic.<br><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1136\" height=\"1204\" src=\"https:\/\/online.berklee.edu\/takenote\/wp-content\/uploads\/2023\/02\/04Circle-of-fifths-sharps-on-staff-lines.jpg\" alt=\"Another way of looking at the sharps in the circle of fifths is to look at the relationship between intervals on staff lines.\" class=\"wp-image-19047\"\/><figcaption class=\"wp-element-caption\">Another way of looking at the sharps in the circle of fifths is to look at the relationship between intervals on staff lines.<\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>When writing music in a key that contains sharps or flats, it is convenient to use a key signature. A <strong>key signature<\/strong> is a collection of all sharps or flats necessary in a given scale, and it appears at the beginning of each staff right after the clef. The key signatures can contain up to seven sharps and seven flats, respectively.&nbsp;<\/p>\n\n\n\n<p>Here are the key signatures, showing an increasing number of sharps. The key signature with seven sharps indicates that all seven notes in the scale carry a sharp, so it is for the key of C\u266f major or its relative minor, A\u266f minor.<br><\/p>\n\n\n\n<figure class=\"wp-block-image\"><img loading=\"lazy\" decoding=\"async\" width=\"1490\" height=\"384\" src=\"https:\/\/online.berklee.edu\/takenote\/wp-content\/uploads\/2023\/02\/05Circle-of-fifths-Staff-lines.jpeg\" alt=\"It is helpful to look at the circle of fifths in many different ways, and this is how the sharps look on staff lines.\" class=\"wp-image-19048\"\/><figcaption class=\"wp-element-caption\">It is helpful to look at the circle of fifths in many different ways, and this is how the sharps look on staff lines.<\/figcaption><\/figure>\n\n\n\n<p><\/p>\n\n\n\n<p>It is very important to remember the order of the seven sharps: <strong>F C G D A E B<\/strong>. Notice that they go up a P5 from one to the next. Knowing the exact placement of the sharps on the staff is also important, especially the position of the fifth sharp, A\u266f, on both clefs. Practice writing them by hand, thinking about the name of the major scale for each key signature.<\/p>\n\n\n\n<p>When we look at the circle of fifths, you\u2019ll see that each letter represents a key. The circle looks like a clock, with 12 notches. If you go in the clockwise direction, each key is a <strong>P5 higher <\/strong>than the previous one, and the number of sharps increases for each ascending P5.
