[what is Qactus?]

This weird tool is made in Japan.
Qactus can increase guitar players all over the world without any great leaders or teachers.
it was made for it. i believe Qactus will break through something difficult related to music.
Qactus is for people without any previous experience on any musical instruments. now we should believe that anyone can play guitar, because of Qactus. it’s a bit hard to tell the details because it’s not existing yet.
i think this description will help:
Qactus has three ways in helping beginners out [1] Qactus helps you know the condition of your guitar. The physical condition of guitars may change depending on how the user uses or stores it. These changes may affect the performance of the guitar when played. Sometimes, the guitar no longer remains a musical instrument. However, most beginner guitar players do not know this and sometimes they attribute the imperfect production of music to their skills without knowing that the guitar itself may have caused the problem. It sometimes results in the frustration on the part of the player. Aspiring guitar players should know that the guitar’s condition is a vital factor to the production of good music. Here is the part where Qactus comes in. Qactus will help you determine the condition of your guitar. Qactus can help monitor for the proper condition of your guitar. [2] Qactus minimizes the difficulties you might encounter as a beginner. Being a beginner might be difficult stage to some. You might encounter mistakes or frustrations that may make you want to stop trying do something new. A musical instrument, for one, may seem very difficult to learn. Qactus can transform your guitar into an instrument that is easy to play. A remarkable thing you can do with Qactus is that it decreases the effort you put in pressing the strings, or muting. Difficulties encountered by beginners will be minimized, resulting in a satisfactory musical experience. Due to this, beginners will feel they are improving more. You might even want to play your guitar all the time. Beginners will find that it is easy to master a new song in a short time with Qactus. Qactus works by lessening the difficulties you might encounter so you will have more time to focus on your practice. Qactus is also suitable for those who have given up on practice as it allows them to restart training in an easier way. Qactus will make you feel better. [3] Qactus fosters harmony and friendship between differences. Aside from helping you improve your skill, Qactus will also allow you to meet new people. Through QactusCore and QactusCore-Method, beginner, experts and professional guitar players can meet online to help each other out. Puzzles and diagrams are available to help beginners learn guitar chords in a fun way. Qactus promotes togetherness and cooperation work we see among music groups. Harmony is essential in playing musical instruments but it does not pertain only to music. Harmony among music players is also important. With Qactus, musical harmony and social harmony is possible to be achieved and improved. Qactus’ goal is to help people learn how to play the guitar and to use music in bringing people together. Music is not only the sound we produce in plucking a string, pressing a key or striking a drum. Music is the product of music instrument, people and feelings. Here in Qactus, we believe that “playing music” is not simply a mechanical operation of an instrument to produce sounds as we believe that feelings are an important ingredient in creating music for “feelings are the raw materials of music.”

[What inspired you to create it?] 

my goal is to increase music lovers. i believe this tool will help it well.
my website mentions about it:

i’ve been trying to change people without any previous experience on any musical instruments into music lovers for 15 years.
they made me aware many things related to about how to lead them properly.
and then this tool appeared in my mind.

it has some taboos to avoid letting them give up. it’s very unique.
it will appear on the website on june 1st. named “QactusCore-Method”.
you will be able to figure out all about Qactus if you read it.

it will be better because QactusCore-Method has many pages.
it doesn’t suit on this interview page.

[How long did it take to develop?]

i had been thinking about this kind of thing for 4 years but i didn’t believe it was possible.

but it becomes into a reality because of him, Toshi Torii.

i and Toshi Torii saw each other in tokyo last October.
it was the first time to have a meeting in 2 years.

he is a kind of a genius engineer.
he worked as a leader in Guyatone, Sony, Roland, and so on.

it mentions about him

and, if you need to know about him more, ask DEMONT GUITAR in Chicago.
Mr.Nate is one of the best person who can tell about Toshi Torii because he is the best Guyatone collector all over the world.
i’ll introduce him if you want.

[Can Qactus also help in creating our own songs and compositions as well?] 

could be. just try it. very unique music might appear. but i’m not sure if skilled players will love it or not.
i’d be glad as long as many people use Qactus in front of the public. it will be a great advertisement,lol

i think it’s better for musical education especially people without any previous experience on any musical instruments.
it’s important for music cultures, musical industries, and exchanging information between differences.

[Can Qactus be used by professional guitar players, as well as someone who is buying a guitar for the first time?]

i think they don’t need it anymore because they can play anything they want to sound.
however it’d be cool if many people see Qactus using popular guy. it will be a great advertisement again.. lol
i want professional guitar players to show Qactus if they want many people without any previous experience on any musical instruments to become interested in playing guitar.
it will help to improve many things like relationship between differences through playing music. you must imagine what i mean if you are a professional musician.

[With Qactus being a tool to help music students nurture their growth in guitar playing, is it possible that it can become a curriculum used in all music classes?]

i wrote a manuscript for the website recently.
it will be a great description for this question.
please read this:

Qactus makes students (even without leader’s skills) into teachers who can teach the guitar. What you and your students need are only: Qactus, QactusCore, and guitars.
Teachers won’t need to force students to memorize material but to understand it instead.
Your music class should be able to bring out your student’s hidden talents. There is no hurry to cram all the information into your students.

Qactus Educational Program

I have seen some articles in educational music magazines before like this:

“Why do we need musical education in school?”

It’s a subject in which a class can share emotional experiences together.
It’s a subject which joins intelligence and sensitivity.
It’s a subject which requires a certain amount of concentration and has a focus (musical players should be able to express themselves through music) at the same time.
It’s a subject which refines a person’s feelings.
It’s a subject in which we can learn how to accept reality.

The article made me realize how vitally important music education is even though some people don’t always think so.

In a music class, we should follow what we are interested in.
Sometimes though, we can’t do that because certain instruments are too difficult to make sounds with (even if it were only a note) without a dedicated amount of practice.
However, most people enjoying listening to popular music. They might feel discouraged if they have music classes which exclusively use instruments that are not geared towards popular music.

The guitar is one of the best musical instruments for a music class because it is an essential instrument in playing popular music.
However, new students have to do a lot of basic training before they can enjoy satisfactory results (it usually takes a week or more to get the basic skill set mastered)

Qactus can assist anybody without any previous musical instrument so that they can play a song in class.
Students will quickly feel a sense of accomplishment as they play the songs they love.

The impact of Qactus is important for everyone to take note of, especially teachers: One does not need any special skills to play the guitar.
If students all over the world have access to Qactus, they will even be able to achieve it by themselves.
It’s a work-ready tool for anyone.

Try making a unique lesson using Qactus where you sing, and of course play the guitar. Aside from helping beginners take their first steps on the guitar in a music class, everyone will get something more than they expected: a sense of Harmony.


[what do you envision for Qactus in the next couple of years?]
Qactus will lead people without any previous experience on any musical instruments to their next stage.
they will be able to go over their first step which is hard for beginners.

actually people who can’t control their hands or arms well due to accidents or diseases will be able to play guitar.

as i mentioned it, Qactus has three ways in helping beginners out.
especially i’m expecting this item “[3] Qactus fosters harmony and friendship between differences” works well.
