Sometimes, they don\u2019t even make sense! (At least to me.) In this lesson, I sit down with Sam to discuss some of music theory\u2019s weirder rules. You\u2019ll see that we disagree on whether these rules should be followed, and we each have some very strong opinions!&nbsp;<\/p>\n\n\n\n<p>Here\u2019s what we\u2019ll talk about:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><a href=\"#rule-1\">The Invisible Bar Line Rule<\/a><\/li>\n\n\n\n<li><a href=\"#rule-2\">Ties vs. Slurs<\/a><\/li>\n\n\n\n<li><a href=\"#rule-3\">Types of Staccatos<\/a><\/li>\n\n\n\n<li><a href=\"#rule-4\">Double Sharps and Double Flats<\/a><\/li>\n\n\n\n<li><a href=\"#rule-5\">The Tritone<\/a><\/li>\n<\/ol>\n\n\n\n<p>Now, as much as I disagree with him from time and time, Sam does an <em>excellent<\/em> job explaining all these rules. So, if you\u2019ve ever been confused about the difference between ties and slurs and how to tell them apart keep reading!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rule-1\" style=\"font-size:28px\"><strong>Rule #1: The Invisible Bar Line Music Theory Rule<\/strong><\/h2>\n\n\n\n<p>The <strong>invisible bar line<\/strong> or the <strong>imaginary bar line<\/strong> is a rule for writing sheet music. Imagine that an invisible bar line cuts through each measure of music, splitting it into two equal halves.<\/p>\n\n\n\n<p>The rule is you can\u2019t cross the invisible bar line. This means you typically cannot combine beats 1 and 2.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.musora.com\/musora-cdn\/image\/quality=85\/https:\/\/pianote.s3.us-east-1.amazonaws.com\/blog\/2021\/Music%20Theory%20Rules\/invisible%20barline%20rule%20copy.png\" alt=\"Diagram showing the music theory rule of the invisible bar line. In the first example: 4\/4 time, quarter note-half note-quarter note, marked incorrect with an x. In the second example, 4\/4 time, quarter note-tied quarter notes-quarter note, marked with a green checkmark.\"\/><\/figure>\n\n\n\n<p>In the first, incorrect measure, beats 2 and 3 are combined into one half note. In the second, correct measure, beats 2 and 3 are written separately. But both versions sound the same.<\/p>\n\n\n\n<p>Now, the invisible bar line rule sounds <em>pretty <\/em>unnecessary to me! But according to Sam, organizing measures into two equal parts makes it easier for musicians to read very complex sheet music. For example, this rule can help musicians read <a href=\"https:\/\/online.berklee.edu\/takenote\/imaginary-barlines\/\" target=\"_blank\" rel=\"noreferrer noopener\">syncopations<\/a>.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<span class=\"blue-text-block\">\ud83c\udfb9 <b><i>The invisible bar line rule debate goes on!<\/i><\/b> Interestingly, not everyone agrees that the imaginary bar line makes things easier to read (take that, music theory rules!). In fact, someone did an informal <a href=\"https:\/\/www.miltonline.com\/2015\/03\/22\/beyond-the-imaginary-barline\/\" target=\"_blank\" rel=\"noopener\">poll<\/a> and many musicians seem to prefer the \u201cincorrect\u201d way of writing things\u2026<\/span>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<p>If you want to learn more about this rule, check out <a href=\"https:\/\/online.berklee.edu\/takenote\/imaginary-barlines\/\" target=\"_blank\" rel=\"noreferrer noopener\">Berklee\u2019s music theory lesson<\/a> for a more academic explanation.<\/p>\n\n\n\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<iframe class=\"email-form-include-full\" src=\"https:\/\/www.pianote.com\/weekly-email\" frameborder=\"none\"><\/iframe>\n\n\n\n<div style=\"height:20px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rule-2\" style=\"font-size:28px\"><strong>#2. Ties vs. Slurs<\/strong><\/h2>\n\n\n\n<p>Ties and slurs look way too alike. They both involve sweeping, curved lines across sheet music. So what\u2019s the difference?<\/p>\n\n\n\n<p>Well, when two identical notes are connected, it\u2019s a <strong>tie<\/strong>. A tie is when the note values are added together. So, two quarter notes tied together is basically a half note.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.musora.com\/musora-cdn\/image\/quality=85\/https:\/\/pianote.s3.us-east-1.amazonaws.com\/blog\/2021\/Music%20Theory%20Rules\/slur%20and%20ties%20example.png\" alt=\"Sheet music with slurs and ties labelled.\"\/><\/figure>\n\n\n\n<p>A <strong>slur<\/strong> is when several different notes are connected together with a curved line. (Sometimes, this is called a phrase.) This means that the notes should be played <em>legato<\/em> or connected, and it&#8217;s kind of like singing a series of notes in one breath.<\/p>\n\n\n\n<p>See, my question is this: why don\u2019t we just invent different symbols for each thing? Like have a squiggly line mean a slur?? Well, Sam\u2019s answer is that this is just convention handed down to us from the people who made the rules.<\/p>\n\n\n\n<p>This explanation doesn\u2019t satisfy me, but it\u2019s too late in history to change things!<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rule-3\" style=\"font-size:28px\"><strong>#3. Types of Staccato<\/strong><\/h2>\n\n\n\n<p>You may have seen a <strong>staccato<\/strong> and a <strong>tenuto<\/strong>, but have you heard of <em>staccatissimos<\/em> and <em>mezzo staccatos<\/em>?!<\/p>\n\n\n\n<p>These little articulation markings are <em>super specific <\/em>types of staccato!<\/p>\n\n\n\n<div class=\"wp-block-columns are-vertically-aligned-center is-layout-flex wp-container-core-columns-is-layout-9d6595d7 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-vertically-aligned-center is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.musora.com\/musora-cdn\/image\/quality=85\/https:\/\/pianote.s3.us-east-1.amazonaws.com\/blog\/2021\/Music%20Theory%20Rules\/staccato%20differences.png\" alt=\"Staccato: quarter note with dot underneath.

And Sam says I have a point! But knowing the tools to express musical feeling on paper can also be useful.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rule-4\" style=\"font-size:28px\"><strong>#4. Double Sharps and Double Flats<\/strong><\/h2>\n\n\n\n<p>Yup, you can double-sharp and double-flat a note.<\/p>\n\n\n\n<p>Double-sharps look like an \u201cx\u201d and double-flats are just two flats. A double-sharp raises a note\u2019s pitch up by two semitones, and a double-flat lowers a note\u2019s pitch down by two semitones.&nbsp;<\/p>\n\n\n\n<p>In this example, F double-sharp is the same note as G. And G double-flat is the same place on the keyboard as F.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"https:\/\/www.musora.com\/musora-cdn\/image\/quality=85\/https:\/\/pianote.s3.us-east-1.amazonaws.com\/blog\/2021\/Music%20Theory%20Rules\/Double%20Sharp%20and%20Flat%20copy.png\" alt=\"F double sharp on staff and location highlighted in red on keyboard. G double flat on staff and location highlighted in red on keyboard.\"\/><\/figure>\n\n\n\n<p>So, here\u2019s the obvious question: why don\u2019t we just write G and F for these two cases?!<\/p>\n\n\n\n<p>Here&#8217;s how Sam explains it: double sharps and double flats prevent the key signature from interfering with a natural sign if there was ever to be one in a challenging key. So, double sharps and flats allow us access to the natural notes we want to use without having to change the key signature.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"rule-5\" style=\"font-size:28px\"><strong>#5. The Tritone<\/strong><\/h2>\n\n\n\n<p>The tritone is a funky, crunchy sounding interval that exists between a perfect fourth and a perfect fifth.<\/p>\n\n\n\n<p>Another way to describe this is an interval three whole steps apart.<\/p>\n\n\n\n<p>When it comes to intervals, most intervals have a major version and a minor version; for example, we have major thirds and minor thirds.&nbsp;But perfect fourths and fifths don&#8217;t have two versions.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"371\" src=\"https:\/\/www.musora.com\/musora-cdn\/image\/quality=85\/https:\/\/pianote-blog.s3.us-east-2.amazonaws.com\/wp-content\/uploads\/2022\/07\/11082738\/tritone2-1024x371.png\" alt=\"Keyboard diagrams under staff images of perfect 4th, augmented 4th (tritone), diminished 5th (tritone), and perfect 5th.\" class=\"wp-image-8358\" srcset=\"https:\/\/pianote-blog.s3.us-east-2.amazonaws.com\/app\/uploads\/2022\/07\/11082738\/tritone2-1024x371.png 1024w, https:\/\/pianote-blog.s3.us-east-2.amazonaws.com\/app\/uploads\/2022\/07\/11082738\/tritone2-300x109.png 300w, https:\/\/pianote-blog.s3.us-east-2.amazonaws.com\/app\/uploads\/2022\/07\/11082738\/tritone2-768x278.png 768w, https:\/\/pianote-blog.s3.us-east-2.amazonaws.com\/app\/uploads\/2022\/07\/11082738\/tritone2.png 1200w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>However, we can narrow a perfect fifth by one half-step or widen a perfect fourth by one half-step.
