Dots, Ties, and Triplets in Kalimba Tablature
You can fine tune the length of a note with these three notation tools
The standard types of notes last 1 beat, or 2 beats, or 4 beats... or going the other way, 1/2 beat, or 1/4 beat, or 1/8 beat. What if you want to play a note that lasts some other length, like three beats, or 3/4 of a beat?
There are two modifications of the standard notation system - dots and ties - that modify the length of the basic note types to give you a note that lasts other lengths. We give instruction on how to build longer composite notes with dots and ties.
Those dots? No, they are "repeat signs"
First, let me be clear about what I am NOT talking about. The "open repeat sign" is a double horizontal bar line with two dots above it, and the "close repeat sign" is a double bar line with two dots below it. When you get to the "open repeat sign", breeze through it and remember where it is. When you get to the :close repeat sign", immediately jump back to the "open repeat sign". That is, the "open repeat" marks the beginning of a looped section, and the "close repeat" sign makes the end of a looped section.
In other words, the repeat signs do have dots, but have nothing to do with dotted notes.
The "tie" binds two or more notes into one note
Two or more notes connected with a tie are played as a single note that lasts as long as all of the tied notes combined.
The whole note in measure 1 gets 4 beats, and the quarter notes in measure 2 each get 1 beat. The tie - the curved line in measure 1 which can be seen on the red column (the "A" tine) - ties the whole note together with the first quarter note, and the composite note lasts a total of 5 beats.
A tie can syncopate
The rhythm in the first measure is very straight: "One and two and three and four - " - or perhaps "I can jump up on the bed". In the second measure we have tied the second and third eighth note to each other, counted as "one and-two and three and four" where the "and-two" makes one longer beat - or "jump UP - upon the bed."
The tie joins two eighth notes, each lasting half a beat, making a single note that is held for a total of one beat. Interestingly, this tied note starts on the off-beat (on the "and" just after the "one." When you get to the next down-beat on "two," no note is played (in the recording, you can hear this "naked 2 count"). When you play on the off-beat and don't play on the down-beat, you likely have syncopation.
Dots add 50% to the length of the note
The tie in measure 1 combines the half note (2 beats) and quarter note (1 beat) to create a single note that lasts 3 beats. Measure 2 creates the same music with different notation - the dot immediately after (above) any note will add 50% to the length of the note. As the note in measure 2 is a half note getting 2 beats, the dot instructs us to add 50% of 2 = 1 to the length of the note, for a total of 3 beats.
Measures 3 and 4 illustrate the same concepts, but the notes are coming twice as fast. The tie between the quarter note (1 beat) and the eighth note (half a beat) in measure 3 results in a single note getting 1.5 beats. Similarly, the quarter note with the dot after it in measure 4 - called a dotted quarter note - gets 1.5 beats.
These dotted quarter / eighth note figures create a lopsided feel, with the emphasis placed on the long first note, and a lighter touch on the short following note. Another way to think about this is that the short eighth note is a lead-in to the following dotted quarter note.
Dotted Eighth / Sixteenth - A Galloping Rhythm
In this example, every group of notes that is beamed (connected at the left edge of the tablature) together gets a total of 1 beat. In measure 1, there are four groups of three notes beamed together - an eighth note getting 0.5 beats, and two sixteenth notes each getting 0.25 of a beat. This is counted as "One and-a two and-a" - or as we write it here, "One An-A two An-a..."
In measure 2, we create a single note out of the eighth and the first sixteenth notes by tieing them together. That tied note lasts 0.5 + 0.25 = 0.75 of a beat, and it is followed by a sixteenth note to make up the remaining 0.25 of the beat. The first note lasts 3 times longer than the second note. This lopsided pairing of notes can make the music feel as if it is galloping.
In measure 3, we create the exact same rhythm by using the dot instead of the tie. The eighth note gets 0.5 of a beat. The dot adds another 50% to the length of the note, which is 50% of 0.5, which is 0.25. Hence the dotted eighth note gets 0.75 of the beat, with the following sixteenth note making up the remaining 0.25 of the beat.
The "dotted eighth / sixteenth" is a very common rhythmic figure in music, and you should learn this and take it with you.
In this example, each group of connected, or "beamed" notes, fills one beat, just as the quarter notes do. Two eighth notes get one beat. Four sixteenth notes get one beat. And if we want to fit in three equal-length notes into a beat, we have what is called a triplet. Triplet notation is three notes with a "3" to the left.
Triplets and the 6/8 Time Signature
What if everything in a song were based on triplets? We could write it out in the standard 4/4 time signature and write each triplet out with the "3" on the left side. But there's an easier way.
The "6/8" fraction in the lower left corner is called the "time signature." Common Time is "4/4" - the first (top) "4" means there are four beats in each measure, and the second (bottom) "4" means the "4th note" - or quarter note - gets one beat. The "6/8" time signature means that there are six beats in each measure, and the "8th note" - or eighth note - gets one beat. That means that six eighth notes will fill a 6/8 measure.
The music is more easily read if we beam the eighth notes together, but it is a convention to not beam across the middle of the measure. This means that in 6/8, the eighth notes are beamed in sets of three - which will sound the same as a triplet.
The dotted eighth notes in measures 2, 3, and 4 each get three beats, or half a measure.
Sometimes 6/8 is counted in other ways - we'll cover that later.
