Piano Tuning Course | Piano Course For Beginning Student | Course For Curent Piano Technicians | Piano Repairing

  • Piano Training Course

The Electronics4you, the organization of the Registered Piano Technician, is the premier source of expertise in piano service and technology. Our Resources area has information for tuners, technicians, teachers, piano owners and pianists. A career in piano technology is unique and very rewarding. After completing this course you will be able to work in concert halls, colleges and universities, recording studios, retail stores and in many other exciting settings.

  • Skilled Required
    Normal hearing, patience, average finger dexterity, and a willingness to learn are needed in this field. A musical background is not required. Skills and knowledge in cabinetmaking and piano design are important for those who are interested in piano rebuilding. Whether you enroll in an established school, apprentice with another technician or choose to study on your own, a core curriculum in piano technology typically includes the following subjects:


  • Tuning Theory and Terminology.
  • Tuning Procedures.
  • Piano Parts and How They Function.
  • Common Field Repairs.
  • Action Regulation.
  • Tone Regulation.
  • Business Practices.
  • Piano History and Design.

Piano technicians are trained to tune, repair and adjust pianos to improve their sound and touch. Full-service piano technicians can diagnose problems in the mechanical functioning of pianos and fix those problems so owners can enjoy their pianos for years to come.

  • Working Conditions

The majority of piano technicians are self-employed. Others work for music stores, other technicians, manufacturers, school systems, colleges and universities, or in other institutional and performance settings. Piano technology is a good profession for those who like to work ndependently. Because most work is done in private homes, it offers a flexible schedule and a large amount of local travel. Piano technicians report a high level of job satisfaction, a low stress level, and a serious commitment to continued personal and professional growth.

  • What You Will Learn In A Piano Technology Training Program

  • Whether you enroll in an established school, apprentice with another technician or choose to study on your own, a core curriculum in piano technology typically includes the following subjects:

    Advanced training may include the skills and knowledge needed for concert tuning, specialty repairs, reconditioning, and rebuilding.
    If you decide to start your own business you will want to seek training in the operation of a small business, financial management, taxation, marketing, and customer service. Technicians usually own their own tools, so plan on making an investment in supplies and


  • The Piano School is the India centre of excellence for piano tuning, restoration and repair, designed for those who wish to work in the piano industry as a tuner or technician. This 2 year course is designed to prepare successful learners with the skills needed to join the piano trade. It develops skills, techniques and understanding to a level based on commercial standards of quality and time.

    This course builds on the basic level 2 course and covers more advanced aspects of piano tuning on both Digital Piano & Manual Piano. It also includes everything from minor maintenance tasks typically performed on a customer's piano, to full workshop restoration and refurbishment.

    The course is workshop based and is involves demonstrations becoming more self directed as concepts and techniques are practised. Main elements include: upright and grand piano fine tuning, restringing, action (hammer mechanism) overhaul of upright and grand pianos, setting up and regulating, case restoration and polishing. This level includes the study of acoustics and prepares students for employment or self employment by introducing basic business planning and practices.

  • This course will take you from the very basics and show you how to tune a piano, where to put the mutes, what notes to tune in what order, etc.
  • It will also teach you the tricks needed to make tuning a piano as easy as possible. Tuning can be a very stressful and difficult skill to learn, but it doesn't have to be. With this course you will learn what to listen for when tuning, how to make fine adjustments, how to keep the pitch stable, etc.

  • Techniques employed will be self evaluation using a mock exam spreadsheet and piano tuning software, and peer collaboration. Students are required to bring a laptop with a working microphone and battery or extension cord.

    Areas of concentration will be:
    - Quick and accurate tuning of the temperament.
    - Consistent octave sizes.
    - Achieving accurate stability quickly without excessive test blows.
    - Speed.



Musical Keyboard Training For Repairing | Musical Keyboard Chip Level Repairing | Musical Keyboard Repairing

  • Electronic Keyboard Repair

  • Electronic Keyboards is a generic descriptive term but is often used for a more specific category of electronic musical instrument. In general terms anything that has a piano style keyboard and generates sounds through some process involving electronics. This could include electronic organs, synthesizers, and even electronically enhance acoustic pianos. The term also is often used to refer to a class of portable consumer/semi-professional instruments often with built in speakers. They are often sold in big box stores and warehouse stores as well as conventional music stores. As a category it is poorly defined and subject to individual interpretation. It also becomes blurry as to when it stops being a keyboard on a stand and when it becomes a digital piano, this usually being a marketing decision.

    The most familiar electronic keyboards, and the most dominant in the market, are those made by Yamaha like the PSR series and the Casio lines. There are also so very low cost models with little know brand names that can be found. Portable keyboards designed for the home market have been around since the early 70's and the internal circuitry has pretty much paralleled the development of the home organ. The earliest models used discrete transistor circuitry and consisted of individual tone generators, voice shaping circuits, and a diode or transistor keying array. They have become increasingly more integrated with the most recent models consisting of one or two high density integrated circuits one a single circuit board. The internal speaker systems have shown similar evolution starting with transistor radio type speakers and amplifiers consisting of a few transistors, to todays 3 way speaker systems with ported bass enclosures and tri-amped designs using highly integrated power amplifier modules.

  • Repairing Electronic Keyboards

  • Dirty key contacts and broken knobs, jacks, and keys are the main tasks involved in keyboard repair. Key contacts should be cleaned with plain liquid handsoap that contains no additives live aloe, moisturizers, fragrance, or vitamin E. All the contacts should be cleaned and the enclosure and circuit boards should be swept clean of all contamination. A static resistant portable vacuum is good for cleaning particulate contamination. Static discharge precautions should be used since damage to a critical IC can result in the loss of the entire keyboard since some of the IC's cost nearly as much to replace as the keyboard would cost to replace.

    Most of these keyboards use an external power supply so high voltage is not a worry. The jack that the power supply is plugged into becomes a frequent point of failure as the cords get kicked or the keyboard gets dropped on the jack. Headphone jacks are another frequent point of failure since a failed jack can prevent sound getting to the speakers. Since the ability to use the keyboard with headphones is often one of the motivating factors in their purchase the do get used and abused.

    Cost effectiveness of a repair becomes a major issue at the low end. It takes just as much time to clean the contacts of a cheap keyboard as it does and expensive one. Also parts availability becomes a major issue after a few short years. And ten years down the road it is very unusual to find the replacement parts necessary to make the repair. Even at the higher end the crossover point where it is cheaper to replace than to repair is not all that hard to reach.
