The Dot and the Tie: How to Modify Duration

The System Has Gaps

The rhythm figures we have seen so far form a perfect binary system: each figure lasts exactly half as long as the one before it. It is elegant and consistent. But it has a problem: it cannot directly represent every possible duration.

How do you write a note that lasts three beats? Or one that lasts a beat and a half? Note values alone are not enough. For these cases, musical notation developed two complementary tools: the dot and the tie.

The Dot: Adding Half

The dot is a small point placed to the right of a note value. Its effect is always the same: it adds half the value of the figure to itself. A dotted half note lasts three beats: the half note is worth two, the dot adds one more. A dotted quarter note lasts a beat and a half: the quarter note is worth one, the dot adds half. A dotted eighth note lasts three quarters of a beat: the eighth note is worth half, the dot adds a quarter.

The rule is universal and invariable: dotted note = note + half the note. On guitar, the dotted quarter note is one of the most common figures in popular and flamenco repertoire. When you hear that characteristic long-short rhythm in a rumba or a pop melody, there is almost always a dotted quarter followed by an eighth note. That combination occupies exactly two beats: one and a half plus a half.

The Double Dot: Even More Precise

There is also the double dot: two dots to the right of the figure. The second dot adds half the value of the first, meaning one quarter of the original note value.

A double-dotted half note lasts three and a half beats: two from the half note, one from the first dot, and half from the second. It is a less common figure, but it appears in Romantic music and in some jazz styles where subdivision is very detailed.

The Tie: Joining Two Notes Into One

The tie is a curved line connecting two notes of the same pitch. Its effect is simple: the two notes sound as one, with a duration equal to their combined values. A quarter note tied to an eighth note lasts a beat and a half — exactly the same as a dotted quarter note. A half note tied to a quarter note lasts three beats — exactly the same as a dotted half note.

So why does the tie exist if the dot does the same thing? For two fundamental reasons. The first: the tie can cross a barline. If a note begins on the last beat of a measure and needs to continue into the first beat of the next, the dot cannot represent this — the barline would visually interrupt it. The tie can cross the barline and connect the two notes.

The second reason: the tie can create durations that are not simple multiples. A quarter note tied to a sixteenth note lasts five sixteenths of a beat — a duration no dot can represent directly.

How to Execute Them on Guitar

The technical difference between a dotted note and a tied note is zero: in both cases you pluck the string once and let it ring for the full duration. The difference is only in notation.

What does require attention is the counting. A dotted quarter followed by an eighth is an asymmetric rhythm that takes time to internalize. The trick is to practice it with the metronome counting the smallest subdivisions: if the pulse is the quarter note, count in eighth notes — one-and, two-and — and feel that the long note fills 'one-and' and the short note fills only 'two'. Over time, that long-short pattern becomes an automatic physical gesture.

Something to Keep Thinking About

With the dot and the tie, the rhythmic system can represent virtually any duration. But there is one dimension of musical time we have not yet explored: the pulse, that invisible unit that organizes everything we have seen. What exactly is the pulse? Where does it come from? Why does the human body feel it before the mind processes it? That is what we will explore in the next post.
