Description

Technical Field

[0001] The invention relates to the technical field of guitar chord practice, in particular to a guitar chord practice card. Background Art

[0002] As one of the most popular string instruments in the world, mastering chords is the key to learning guitar. After mastering the basic chord fingering, you can play and sing most songs. However, chord practice is quite difficult, and many beginners give up because they find it difficult to break through this bottleneck. Therefore, it is of great significance to develop an effective guitar chord auxiliary practice device.

[0003] Guitar chord trainers in the prior art generally have the following problems: First, some products only use simple icons or text to mark chord positions, making it difficult for practitioners to quickly map them to the specific frets and strings on an actual guitar fretboard, resulting in low learning efficiency. Second, some key-operated auxiliary devices use buttons to simulate string pressing. The feedback force and tactile feel of the buttons differ significantly from those of pressing real guitar strings, leading to problems such as fingering misalignment and improper force control when pressing strings on a real guitar. This is because key-operated operation fails to cultivate correct finger touch, force perception, and muscle memory, making it difficult to effectively transition from auxiliary practice to actual performance. Furthermore, traditional guitar chord trainers are relatively simple to fix, often using adhesive fixation. This can easily cause the device to shift during practice due to hand movements or guitar vibrations, affecting its effectiveness. These combined problems limit the efficiency and practicality of existing chord training devices in assisting chord practice, making it difficult to meet users' needs for efficient and accurate practice. Therefore, a guitar chord practice card is proposed. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the present invention provides a guitar chord practice card to solve the above technical problems.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a guitar chord practice card, comprising a card-shaped card body and finger holes provided on the card body, wherein the thickness of the card body is less than the thickness of the space between the guitar strings and the guitar fingerboard, so that the addition of the card body will not affect the playing of the guitar, and the finger holes are through holes that pass through both the front and back surfaces of the card body, the number of the finger holes being provided is adapted to the number of fingers required for the guitar chord fingering corresponding to the chord card, and the positions of the finger holes being provided correspond to the string-pressing positions of the guitar chord fingering corresponding to the chord card, and the surface of the card body is provided with contact blocks, and the contact blocks are distributed in areas of the surface of the card body that are not covered by the guitar strings, and their distribution positions also avoid areas that are accessible to the guitar strings when they are stationary or playing; a clamping block is also provided on the top of the front end surface of the card body to assist in limiting the installation of the card body;

[0006] The fret slot is opened on the card body, and a fret connecting bridge is provided on the groove of the fret slot, and the fret connecting bridge connects the card body cut off by the fret slot; the opening position of the fret slot corresponds to the position of the frets of the guitar. In the working state, the fret slot covers the outside of the guitar frets at the corresponding position, and the fret connecting bridge is a raised structure, which spans the outside of the guitar frets at the corresponding position, thereby realizing the limitation of the card body.

[0007] Preferably, the clamping block and the card body are an integrated structure, and the number of the clamping blocks is one or more. The clamping block is arranged between the guitar strings. By clamping the clamping block with the capo, the card body can be assisted in limiting the installation, thereby improving the installation stability.

[0008] Preferably, the opening edge of the finger hole is circumferentially provided with a finger mark, and the finger mark is a color mark, a symbol mark or a text mark.

[0009] Compared with the prior art, the present invention provides a guitar chord practice card with the following beneficial effects:

[0010] The guitar chord practice card uses finger holes on the card body that fully match the target chord fingering to directly prompt the practitioner to the correct finger pressing position, allowing the practitioner to quickly determine the placement of each finger. This is especially effective in blind practice. When the finger pressing position deviates from the correct area, the touch blocks on the card body will provide intuitive tactile feedback through physical protrusions, prompting the practitioner to make adjustments in time, helping the practitioner to quickly familiarize themselves with the chord fingering position, effectively forming correct muscle memory, greatly shortening the practice cycle, and significantly improving practice efficiency.

[0011] The thickness of the guitar chord practice card is less than the thickness of the space between the guitar strings and the fretboard, and the contact block, clamping block and other components are distributed in an area away from the strings. When inserted from a higher position near the guitar body, the natural state of the strings will not be affected. The fret slots correspond to the positions of the guitar frets, and the fret connecting bridge can stably limit the card body to the position of the guitar frets. The clamping block protruding above the strings can be used with the capo to further fix the card body, ensuring that it does not move during practice and preventing the capo from contacting the strings and causing interference. Installation, removal and replacement are quick and convenient, meeting the switching needs of different chord practice.

[0012] The finger holes of this guitar chord practice card adopt a through-hole design that runs through both the front and back of the card body, so that the practitioner can retain the same original touch as pressing the strings directly when pressing the strings. The use of practice tools will not affect the perception of the pressure and touch of the strings, making the practice closer to the actual playing state, which helps the practitioner better master the string pressing technique.

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The present invention provides a technical solution, please refer to Figure 1 A guitar chord practice card comprises a card-shaped card body 1 and finger holes 2 provided on the card body 1. The thickness of the card body 1 is less than the thickness of the space between the guitar strings and the guitar fingerboard, so the addition of the card body 1 will not affect the playing of the guitar. The finger holes 2 are through holes running through the front and back of the card body 1. The number of finger holes 2 is adapted to the number of fingers required for the guitar chord fingering corresponding to the chord card, and the positions of the finger holes 2 correspond to the string-pressing positions of the guitar chord fingering corresponding to the chord card. Contact blocks 3 are arranged on the surface of the card body 1, and the contact blocks 3 are distributed in the area of ​​the surface of the card body 1 that is not covered by the strings, and their distribution position also avoids the area that can be touched by the guitar strings when they are stationary or playing. A clamping block 4 is also provided on the top of the front end surface of the card body 1 for assisting in limiting the installation of the card body 1.

[0019] The fret slot 11 is provided on the card body 1, and a fret connecting bridge 12 is provided on the notch of the fret slot 11. The fret connecting bridge 12 connects the card body 1 cut off by the fret slot 11. The opening position of the fret slot 11 corresponds to the position of the frets of the guitar. In the working state, the fret slot 11 covers the outside of the guitar frets at the corresponding position. The fret connecting bridge 12 is a raised structure, which is used to span the outside of the corresponding guitar frets in the fret slot 11, thereby limiting the entire card body 1 on the guitar.

[0020] The clamping block 4 and the card body 1 are an integrated structure, and the number of the clamping block 4 is one or more. The clamping block 4 is arranged between the guitar strings. By clamping the clamping block 4 with the capo, the card body 1 can be assisted in limiting the installation and improving the installation stability.

[0021] An indicator mark 5 is provided on the circumference of the opening edge of the finger hole 2. The indicator mark 5 is a color mark, a symbol mark or a text mark.

[0022] When using this solution, you can select the corresponding chord practice card according to the guitar chord fingering to be practiced. The number, position and size of the finger holes 2 on the card body 1 match the finger number, string pressing position and finger contact surface area of ​​the target chord fingering. The finger mark 5 distinguishes the finger holes 2 corresponding to different fingers through color, symbols or text;

[0023] See also Figure 2 When working, first insert the card body 1 into the gap between the strings and the fingerboard from the position where the strings are higher, close to the guitar body. The thickness of the card body 1 is smaller than the gap between the strings and the fingerboard, and other components also avoid the strings and do not interfere with the strings, thus ensuring that the natural state of the strings is not affected during the insertion process;

[0024] Move the card body 1 along the guitar neck toward the guitar head, so that the fret slots 11 on the card body 1 are aligned with the fret positions on the guitar fingerboard;

[0025] Use a guitar-specific capo to clamp the clamping block 4 on the upper front of the card body 1 to fix the card body 1 to the guitar body to ensure that the card body 1 does not move during practice;

[0026] The practitioner presses the strings with the corresponding fingers according to the position of the finger holes 2 and the prompts of the finger mark 5, and passes through the finger holes 2 to the guitar fretboard. The contact blocks 3 are distributed on the surface of the card body 1. The finger holes 2 are the correct finger positions in the current chord practice state. When the finger pressing position deviates from the correct finger position area, it will press the contact block 3. The contact block 3 will provide more intuitive tactile feedback through physical protrusions, prompting the practitioner to adjust the pressing position.

[0027] When the present invention is used, the chord card is inserted between the strings and the fingerboard from a position higher than the strings near the guitar body, and then moved to the headstock to a suitable position. At this time, the guitar frets are accommodated in the fret slots 11, and the card body 1 is close to the guitar fingerboard and is located under the guitar strings. A guitar-specific capo can be used to clamp the chord card and the guitar headstock at the clamping block 4 to fix them. The clamping block 4 protrudes above the guitar strings to prevent the guitar capo from contacting the guitar strings and causing interference; a fixing clip, a capo, etc. is used to clamp the card body 1 of the chord card and the guitar body at the clamping block 4 to fix them. Different chord cards correspond to different chord fingerings. Practitioners can select the corresponding chord card according to the chord to be practiced (for example, if you choose the F chord, please refer to Figure 3 ), quick and easy disassembly and replacement.

[0028] The present invention prompts the finger pressing position through the finger position hole 2, and the through-hole design of the finger position hole 2 allows the practitioner to retain the original touch when pressing the strings. The finger mark 5 can indicate the corresponding finger. When practicing chord fingering, especially blind pressing practice, if the finger pressing position deviates, the prompt contact block 3 will give the practitioner a reverse prompt in tactile sense so that the pressing position can be corrected in time. The use of the present invention will facilitate the practitioner to become familiar with the chord fingering position, quickly form correct muscle memory, and greatly improve the practitioner's practice efficiency.
