Uke Glossary
Ukulele Anatomy:
- Upper Bout - the upper bulge in the instrument's body
- Lower Bout - the lower bulge in the instrument's body (almost always the larger of the two)
- Scale Length - the average sounding length of the strings (to help the instrument's intonation, the saddle is angled so that the bass strings are slightly longer than the treble strings. The scale length is usually measured as the distance between the nut and the center of the 12th fret, multiplied by 2)
- Body Length - the length of the body section of the guitar, not including the heelblock
- Body Depth - the depth of the body (measured at its deepest point).
- Total Length - the length of the entire instrument.
- Nut Width/Fingerboard Width - the width across the end of the fingerboard where it meets the nut.
- String Spacing at Nut - the distance between the 1st and 4th strings at the nut.
- String Spacing at Bridge - the distance between the 1st and 4th strings at the bridge, measured at a right angle to the strings.
- Saddle Width - the width of the saddle.
Ukulele Sizes are determined by scale length:
- Soprano/Standard: Smallest size in the ‘ukulele family, the soprano has the recognizable plinky sound that everyone associates with the instrument.
- Super Soprano: Soprano body with an extended neck and a 15-16 in. scale.
- Concert: Medium size with a scale length of 15-16 in.
- Super Concert: Has an extended neck with a 17 in. scale
- Tenor: What most of the pros play, 17-18 in scale, gives a deeper, and usually richer tone with more sustain and depth.
- Super Tenor: Has a 17 in scale on a larger body .
- Baritone: A baritone is like a small guitar missing the two top strings. It is biggest of all and the different tuning requires some knowledge or quick transposing to figure out the chords.
Abalone: A highly prized shiny material obtained from shells and often used on ukulele fret marker inlays, on headstocks, or on binding around the edge of the instrument or around the soundhole.
Action: Referring to the height of the strings above the frets and fretboard.
Active Pickups: Usually louder and brighter. It also allows you to shape the sound of the pickup in a number of ways: volume, bass, midrange, treble, gain, phase, etc. Generally, the more expensive the cost, the more control it provides.
Arpeggio: A broken chord, usually played evenly low to high and back again.
Barre chord: From the French term barré. The technique of placing the left hand index finger over two to four strings in the fingering of a chord. The great advantage of using barre chords is that they are "moveable shapes" that can be applied at practically any fret.
Bending: The act of pushing or pulling a string sideways across the a fret to raise the pitch of a note by a half to full tone or more. Used extensively in rock and blues playing as well as in jazz.
Binding: The plastic strip around the edge of the soundboard, disguising the join between the soundboard and the sides of the guitar, and protecting the corners from being damaged. Although plastic is stronger, some manufacturers prefer to use wood for a more traditional appearance.
Bound fingerboards are also common - in this case a plastic or wooden strip is fitted around the edge of the fingerboard to disguise the ends of the frets.
Book Matching: Process by which a plank of wood is sawn down the middle and opened up like a book, so that the resulting two pieces are near mirror images of each other. The grain pattern of a 'book-matched' soundboard should reflect this symmetry.
Bracing: Strips of wood glued to the underside of the soundboard, which add strength, and help to transmit the vibration of the strings around the soundboard. The pattern of these struts varies between the different builders/manufacturers, and is part of what helps to give each make and model its own unique sound.
Break Angle: The downward turn of the strings behind the bridge and/or in front of the nut. The string area between the nut and bridge would be considered to be 0 degrees and perpendicular to that would be 90 degrees. So, an average Ukulele bridge break angle would probably be around 35 degrees.
Bridge: The block of hardwood (usually rosewood or ebony) attached to the soundboard, that holds the saddle, and where the ends of the strings are secured via tying, bridge pins or string knots. Three common types of bridges.
- Tie Bridge:
- Pin Bridge:
- Pull through:
Bridge Pins: The small plastic pins (sometimes wooden on more expensive instruments) that fix the ends of the strings into the bridge. Sometimes these are replaced with heavier brass bridge pins, which can help to increase sustain, improve tone, and eliminate problems with wolf notes.
Bridge Plate: Piece of material on the sound board, under the bridge and inside of the body. It helps to reinforce the sound board from distorting under the pull of the strings on the bridge.
Capo: Capodastère in French, and Capo d'astro in Italian. In Italian, it means “head of fretboard.” Italian musicologist Giovanni Battista Doni reportedly first used the term in his book Annotazioni of 1640. A mechanical device that attaches to the neck by means of a string, spring, elastic or nylon band, or a lever and thumbscrew arrangement. The capo can be used to raise the key of a song to suit a vocalist as well as to lower the action and shorten the string length. Capos come in all styles, and can help your songwriting and playing.
Chromatic Scale: In Western music there are twelve steps between a note in one scale and the same note in the scale either below it or above it. e.g. C, C#, D, Eb, E, F, F#, G, Ab, A, Bb, B and then it arrives back at C
Chunking: A technique used to add a percussive sound to your strum; basically the equivalent of clapping, using your strings
Compensated saddle: These have a ridge that alternates between the front and back edge of the saddle, allowing for the difference in string tension between the plain and wound strings, and thus improving the intonation.
Course: A fancy name for a string i.e. 1st course = A, 2nd course = E
Cutaway: Commonly found on electro-acoustics, a cutaway makes it easier to reach the highest frets on the guitar, and play higher notes - particularly popular with guitarists who mainly play electric guitar, but want an acoustic as well. Some purists argue that acoustic with a cutaway don't sound as good. The acid test is to play it - if you like it, that's all that matters!
Direct In Boxes (DI Boxes): takes a high impedance, unbalanced signal and converts it to a low impedance, balanced signal. This allows the signal to be sent over long cable runs with significantly less signal loss (especially in high frequencies) due to the lowering of the impedance, and greater rejection of interference due to the benefit of common mode rejection in a balanced signal. Furthermore, the lower impedance (around 600 ohms is normal) allows an insignificant load to the input of a mixing console or preamp which is also designed to accept input from low impedance microphones. Can be either Active or Passive.
