Description

Editorial Note 2013101577 There are 2 pages of Description Complete Patent for: Mechanical Chord making Device Formally: referred to as a: Guitar Keyboard I.Provisional} Multi string cord musical instruments This Complete patent application relates to a device to attach to guitars to improve and simplify the use of the guitar. A type of"Guitar Keyboard". The patent also applies to Ukuleles, banjos and similar multi stringed musical instruments. One of the biggest difficulties in learning and playing the guitars and similar string instrument is, being able to "make {form} the chords. This is a process of depressing the strings with fingers onto the wooden neck to create different sounds [notes }. Using more than one finger: say two three or four, and changing from strings, to string combinations on the neck of the guitar is a major task. The space available on the neck is very limited and depressing these strings in rapid succession and changing fingers and string combinations takes many hours practice and very much patience. Many learners just give up. The fingers also get sore and develop blisters and calluses To overcome these problems this patent device allows for; a multitude of strings to be depressed with one finger at once by metal "keys" having a number of rubber "fingers" on each "key", Refer Drawing: Mechanical Chord Making Device Rubber tips' but could be made of other suitable materials This attachment would most likely be made of metal. Other materials such as plastics and composites could be used to make this product. A single finger on a larger plate covering a larger number of strings and having a large area to place fingers is easier than two or three bare fingers on close string positions.

As this attachment covers all the strings, the palm or fingers will not rub, in error against any of the strings. This action, would muffle the sounds, making the use of the guitar much more difficult to play. The drawing will show how groups of strings can be depressed with one finger by pressing an appropriate chosen metal plate [key] over the strings on the neck of the guitar The instrument could cover the full length of the guitar neck but most likely only the first three or four frets on the neck. Drawing: Mechanical Chord Making Device. This shows the 6 keys mounted on to the housing by means of piano hinges. The holes in the keys are for fixing the "rubber finger tips" to depress the strings below, on the fret board {guitar neckI The fingertip positions and key can be changed to suit requirements.
