Although there are various classes of seventh chords, we&#8217;ll be limiting our scope to these seven classes of seventh chords:<\/p>\n<ul>\n<li>The major seventh<\/li>\n<li>The minor seventh<\/li>\n<li>The dominant seventh<\/li>\n<li>The half-diminished seventh<\/li>\n<li>The minor major seventh<\/li>\n<li>The augmented major seventh<\/li>\n<li>The diminished major seventh<\/li>\n<\/ul>\n<p>So let\u2019s get started with this study by taking a look at the concept of the octave.<\/p>\n<h2>An Overview Of The Concept Of The Octave<\/h2>\n<p>Octave takes its root from the Latin word <i>\u2018octava\u2019<\/i> which means <i>eight.<\/i> Octave literally means <strong>eight<\/strong>. The octave is important in music for a variety of reasons.<\/p>\n<p><em>&#8220;Check it out&#8230;&#8221;<\/em><\/p>\n<p>There are seven natural pitch classes on the keyboard from A to G:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=A,B,C,D,E,F,G,A,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026which is usually labeled from C to B:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,D,E,F,G,A,B,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026for the case of simplicity.<\/p>\n<p>If you are highlighting the natural pitch classes on the keyboard, you will have these first seven notes. Beyond these seven, if you take one more step from the seventh tone, you will be getting to the eight tone &#8211; which is a duplicate of the first note that you started out from.<\/p>\n<p>So from C to B:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,D,E,F,G,A,B,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026seven pitch classes [seven notes].<\/p>\n<p>If we make it eight notes, the eighth note (which is C):<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026is the <i>octava<\/i> which literally means <i>eight<\/i> of this C:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\nSo when the term octave is used, it means that this C:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026is eight notes higher than this C:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\nSo that\u2019s the concept of the octave. Check out our lesson on the four dimensions of the octave.<\/p>\n<p>Also take note that the octave can also be an eighth below. So the octave of this C:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026is this C:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=C,,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\nHaving reviewed the concept of the octave, let&#8217;s proceed to the octave shrinking technique.<\/p>\n<h2><i>\u201cWhat Is The Octave Shrinking Technique?\u201d<\/i><\/h2>\n<p>The focus of the octave shrinking technique is to make the octave smaller. Although there are so many steps to take in diminishing the size of the octave, in this lesson we\u2019ll be taking two steps:<\/p>\n<ul>\n<li>Shrinking it by a <em>half step<\/em><\/li>\n<li>Shrinking it by a <em>whole step<\/em><\/li>\n<\/ul>\n<p>An octave can be shrinked by lowering its higher pitch. For example the C octave (C-C):<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026can be shrinked by lowering its higher pitch (C):<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n&#8230;by a <strong>half step<\/strong>. Lowering this C:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n&#8230;by a half step (to B):<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,B,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n&#8230;produces C-B:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,B,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\nYou can also shrink the C octave (C-C):<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026by lowering its higher pitch (C):<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n&#8230;by a <strong>whole step<\/strong>. Lowering C:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,,C&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n&#8230;by a whole step (to Bb):<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,Bb,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n&#8230;produces C-Bb:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,Bb,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\nIn the first case, we shrinked the octave into C-B:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,B,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026which is a <strong>major seventh<\/strong>. We also shrinked the octave into C-Bb:<br \/>\n<img decoding=\"async\" src=\"https:\/\/hearandplay.cc\/dynamic_image\/pianokeys.php?notes=,,C,Bb,&amp;color=33FF66&amp;size=2\" border=\"0\" \/><br \/>\n\u2026which is a <strong>minor seventh<\/strong>. Altogether, after the shrinking of the octave in both cases we came up with two important intervals&#8230;<\/p>\n<ul>\n<li>Major seventh<\/li>\n<li>Minor seventh<\/li>\n<\/ul>\n<p>These two intervals are important in the formation of seventh chords because they are the intervallic constituents of <a href=\"https:\/\/www.hearandplay.com\/main\/60-common-seventh-chord-qualities-common\">common seventh chords<\/a>.<\/p>\n<h2>Formation Of The Seventh Chords Using The Octave Shrinking Technique<\/h2>\n<p>Various seventh chords can be formed using the octave shrinking technique and I&#8217;ll be showing you how it works in this segment. We&#8217;ll be using different classes of <a href=\"https:\/\/www.hearandplay.com\/main\/four-note-triads\">four note triads<\/a>\u00a0 (aka &#8211; &#8220;octave position triads&#8221;) and shrinking them using the octave shrinking technique.<\/p>\n<p><em>&#8220;Let me throw more light on octave position triads&#8230;&#8221;<\/em><\/p>\n<p>A triad is a chord of three notes.
