Description
SYSTEM AND METHOD FOR LEARNING TO PLAY A KEYBOARD INSTRUMENT
The invention relates to a system and method for learning to play a keyboard instrument and in particular to an interactive system for learning to play a keyboard instrument.
If people want to learn to play a keyboard instrument like the piano, they often take lessons to learn how to play the keyboard instrument. In the following such people are referred to as students. In addition to these lessons, students have to practice at home or school without their teacher's guidance and instruction. During such self-practice, students depend on their own audio feedback from the sounds they produce and try to understand whether they are performing correctly. Hence, they learn to play the keyboard instrument based on their own skills. There is no dialogue or direct feedback from their teacher like participating in a lesson in the classroom. In addition, self-practice requires intrinsic motivation from the player to practice the exercises. If there is no direct stimulation from their teacher like participating in a lesson in the classroom, the effect of self-practice will be much less. US 5 252 772 discloses a computer system connected through appropriate analog and digital circuitry that controls or monitors a piano. Solenoids connected to each piano key and to each note-sounding hammer permit a computer program to control the keys and/or the sounding of a note, as well as transmitting to the computer for storage and analysis information concerning a student's performance. In one mode the computer is connected through a control system to physically move the selected keys on the piano and/or to sound the desired note(s). This will assist the student in pointing out the proper keys to play and the required timing, or in playing a duet with the computer. In another mode the control system will record the notes played by a student, as well as the timing and other indicia of technique, in order to store or analyze the performance and assist in correcting errors. With appropriate connections within the piano key actuating devices, the system of this invention can also connect or disconnect the piano key from the hammer, or prevent selected keys from being played.
Although the aforementioned invention supports students to some extent in learning to play the piano, there are some limitations. For example, the feedback is given by a
computerized system that is pre-programmed and has limited flexibility and completely lacks human intuition. There is no opportunity for direct feedback and stimulation from a human teacher that is tailored to the needs of the students.
Hence, an improved system for learning to play a keyboard instrument would be advantageous. In particular, a system for learning to play a keyboard instrument allowing for direct and immediate feedback and stimulation from a human teacher to students, increased flexibility, reduced complexity, and reduced delay would be advantageous.
Accordingly, the invention seeks to provide students with a more interactive, flexible and effective system for learning to play a keyboard instrument, and to provide flexibility and improved teaching capability to teachers to help students learn to play a keyboard instrument.
According to a first aspect of the invention there is provided a system for learning to play a keyboard instrument, the system comprising: a first keyboard instrument with means for generating a first signal representing keys of the first keyboard instrument activated by a first user; and means for transmitting the first signal; means for receiving a first control signal for controlling activation of the keys of the first keyboard instrument; and a controller for receiving the first signal; the controller comprises a second keyboard instrument with means for generating a second signal representing keys of the second keyboard instrument activated by a second user; and means for transmitting the second signal as the first control signal to the first keyboard instrument; and the controller adapted to control activation of the keys of the second keyboard instrument in dependence on the first signal.
Accordingly, a flexible, low complexity and low delay system for learning to play keyboard instruments is enabled. This system allows direct and immediate feedback and stimulation from a human teacher to students. The teacher and students not only play their own keyboard instruments in the same place e.g. home or classroom, but also play their own keyboard instruments in the different places. For example, the teacher plays the keyboard instrument in Copenhagen of Denmark, and the students play their own keyboard instruments in Beijing of China at the same time.
According to a feature of the invention, controlling the activation of the keys comprises activating the keys corresponding to the user activated keys. This allows immediate tactile feedback from the teacher to students. Specifically, the teacher shows which keys should be pressed at a certain time to students when the teacher plays a keyboard
instrument. Therefore, the students can see and feel what keys he/she should use and find out possible mistakes. On the other hand, this allows the teacher to see, feel and evaluate the performance of the student when the students are playing their own keyboard instruments.
According to another feature of the invention, controlling the activation of the keys comprises blocking the keys corresponding to the user activated keys. This allows immediate tactile feedback from the teacher to students. Specifically, the teacher shows which keys should not be pressed at a certain time to students when the teacher plays a keyboard instrument. Therefore, the students can see and feel what keys he/she should not use and avoid making mistakes. According to another feature of the invention, the data type of the first control signal and/or second control signal is a scripting language. This reduces the complexity of transmission. Consequently, enhanced transmittability and reduced delays may be achieved. Specifically, this allows the data transmitted between the teacher's keyboard instrument and the students' keyboard instruments is only the essential information of a few bits e.g. which key is being pressed at given time and not the audio signal or other media signals. Therefore, a real-time bi-directional communication is realized in the feedback loop.
According to another feature of the invention, the first keyboard instrument further comprises at least a storage device for storing the first signal. This allows the asynchronous communication between students and the teacher. Specifically, Students can practice on playing a particular piece firstly, and then the signal is stored in the storage device, so the teacher can retrieve this at any given moment and evaluate the practice performed by students.
According to another feature of the invention, the second keyboard instrument further comprises at least a storage device for storing the second signal. This allows the asynchronous communication between the teacher and students. The teacher can demonstrate how to play a particular piece of a work firstly, and then the signal is stored in the memory, so the students can retrieve this at any given moment and practice on their own keyboard instrument.
According to a second aspect of the invention, there is provided a keyboard instrument for learning to play the keyboard instrument, the apparatus comprises a generator for generating a signal representing keys of the keyboard instrument activated by a first user, and a transmitter for transmitting the signal as a first control signal suitable for controlling the activation of the keys of a second keyboard instrument, and a receiver for receiving a second control signal representing keys of the second keyboard instrument activated by a
second user, and a controller for controlling the activation of the keys of the first keyboard instrument according to the second control signal. This allows students' and teachers' keyboard instruments alone for use in the invention.
According to another feature of the invention, controlling the activation of the keys comprises activating the keys corresponding to the user activated keys. This allows immediate tactile feedback from the teacher to students. Specifically, the teacher shows which keys should be pressed at a certain time to students when the teacher plays a keyboard instrument.

In step 405, which follows step 403, the receiver 114 receives the control signal and controls activation of the keys of the first keyboard instrument. In this method, the teacher plays and his/her keyboard instrument records which keys are pressed. The keyboard instrument saves this in a script which is sent via Internet to the keyboard instrument of the student. The keyboard instrument of the student presses and blocks the corresponding keys automatically.
Fig. 5 is an illustration of a third method for learning to play the keyboard instrument in accordance with an embodiment of the invention. The method will be described with reference to the wireless system of Fig. 2.
In step 501, when the student plays the first keyboard instrument 101 and the teacher plays the second keyboard instrument 102 at the same time. The generator 111 generates a first signal representing keys of the first keyboard instrument activated by the student, and the generator 121 generates a second signal representing keys of the second keyboard instrument activated by the teacher at the same time.
The method proceeds in step 503, wherein the transmitter 113 transmits the first signal to the controller 201, and the transmitter 123 transmits the second signal to the first keyboard instrument 101 at the same time. In step 505, which follows step 503, the controller 201 receives the first signal and is adapted to control activation of the keys of the second keyboard instrument in dependence on the first signal, and the receiver 114 receives the control signal and controls activation of the keys of the first keyboard instrument at the same time.
In this method, the student and teacher play their own keyboard instruments together. Hence, there is a synchronous recording of keys that are pressed at both sites and exchange thereof between the two keyboard instruments, as mentioned in the first method. Since this simple information will require only a few bits, a real-time bi-directional connection between the student and teacher may be realized, which is experienced by the human ear as real time. It will be appreciated that the invention tends to provide one or more of the following advantages singly or in any permutation or combination:
This system allows direct and immediate feedback and stimulation from a human teacher to students.
A remote teaching functionality comprises activating and blocking the keys corresponding to the teacher or students activated keys may be easily achieved. Delays associated with data representing keys of the keyboard instrument activated by a student or a teacher may be significantly reduced. Further advantages will be apparent from the above description.
Although the present invention has been described in connection with the preferred embodiment, it is not intended to be limited to the specific form set forth herein. Rather, the scope of the present invention is limited only by the accompanying claims. In the claims, the term comprising does not exclude the presence of other elements or steps. Furthermore, although individually listed, a plurality of means, elements or method steps may be implemented by e.g. a single unit or processor. Additionally, although individual features may be included in different claims, these may possibly be advantageously combined, and the inclusion in different claims does not imply that a combination of features is no feasible and/or advantageous. In addition, singular references do not exclude a plurality. Thus references to "a", "an", "first", "second" etc do not preclude a plurality.
In general, the invention relates to a system and method for learning to play a keyboard instrument with a direct tactile feedback from a teacher to students.
