These luxuriously equipped solo alto and tenor recorders were developed by recorder maker Maarten Helder especially for today's demanding players. This instrument is intended for the professional performer of nineteenth and twentieth century music. 

Four-Part Adjustable Sound Unit

  • Adjustable Block: By adjusting a screw on the back of the recorder head joint, the height of the windway exit can be varied by raising or lowering the block in place. The player can thereby adjust the block as it swells from moisture or create insteresting variations of sound.
  • Lip Control: Players can narrow the windway entrance by moving the block with lip pressure, creating nuanced changes in timbre and volume. 
  • Adjustable Upper Windway: Players can adjust the height of a plate in the upper windway of the sound-unit to create variations of sound.
  • Variable Windway Covers: The sound-unit comes with small plates to cover the windway, made of different wood types (rosewood, granadilla, Synpor). These can be placed interchangeably as the upper windway ceiling and fixed with a ring. The different structures of the woods result in different tone qualities.

Other Features

  • Extended range: A four-key system makes notes playable through the third octave and a key for the right little finger allows for an extra note on the lower end of the range. This opens up new repertoire for recorder players, such as flute music.
  • Expressive, elegant and dynamic sound: This instrument is assertive and strong, perfect for playing with modern orchestral instruments in modern music, jazz, folk, or traditional settings.
  • Limited fingering modifications: The fingering in the first tow octaves is traditional Baroque. New fingering is only needed in the third octave.
  • Additional piano key: This allows for the fines of dynamic shadings.
  • Synpor-block: This special block provides the instrument with new durability. The core of the block consists of an artificial imitation wood product - synpor - that absorbs the moisture of breath condensation without swelling. The synpor core is embedded into a solid, naturally grown, cedar wood shell. This allows the block to retain its dimensions, even with prolonged playing.

    Damaged or Missing Items

    Shipments should be inspected for damage upon receipt. If there is a problem, save all packing materials and contact us promptly. The shipping company will need to inspect shipping materials in order to approve a claim. If a claim is denied because of missing shipping materials, we cannot offer any reimbursement or replacement.

    If damage is due to a defect in material or workmanship, it may be covered by a manufacturers' warranty. See our warranty page for more information.


    Special Orders

    If you want an instrument that we don't currently have in the store, you can purchase it through a special order. For most special orders we require a partial deposit to get the order started. For some instruments we require the full balance at the outset. Once we receive the final product, we will contact you to pay the outstanding balance. When the full payment has been processed, we will ship the instrument.  If you would like to make a special order, please contact us or place a special order on the product page.

    Special Orders can be cancelled within the first week of placing the order. After the first week we will a cancellation fee of 10-20% of the price of the instrument.


    Made to Order Instruments

    Some of the instruments we carry are made to order. This means that the workshop will only begin crafting the instrument once an order has been placed. For this reason we require a partial deposit to begin an order or, in some cases, will ask for the full balance at the outset. Once we receive the final product, we will contact you to pay any outstanding balance. When the full payment has been processed, we will ship the instrument. If you would like to purchase a made to order instrument, please contact us.

    Please note that, because made to order instruments are made per request, they take longer to craft and ship than other, ready-made instruments. If timing is an issue please let us know before you place your order. We will do our best to accommodate or we will direct you to an alternative option that can be shipped in time.

    All sales on made to order instruments are considered final sales and are ineligible for return. If there is a quality issue or the instrument has been damaged, we will work with you to have the problem fixed. 


    Return Policy

    Instruments can be returned within 30 days provided the instrument is still in like-new condition. If an instrument is returned damaged, stained, or smelling of cigarette smoke, mildew, etc. we cannot offer a full refund. If the instrument can be repaired, we will offer a refund less the cost of repairs. If an instrument is returned after the 30-day window, we can provide a partial refund or we can sell the instrument for you on consignment. 

    Order on made to order instruments are not eligible for returns or refunds. See above for more information. 

    Customers are responsible for all shipping costs.


    How to Return

    We ask that customers contact us before returning instruments. To make a return, pack up each item securely and mail it to our address

    • All wooden instruments that are shipped by air mail must be sealed in an airtight plastic bag. This includes services like Priority Mail, Express Mail, FedEx express, and UPS express among others. If you are not sure how your package will be shipped, use an airtight plastic bag just in case. This step is crucial as instruments dry out under the low air pressure and dry air conditions of air services. This can cause instruments to change dimensions, often irreversibly, resulting in tuning and voicing changes. If an instrument arrives in this condition, we cannot offer a full refund. If the instrument can be repaired, we will offer a refund less the cost of repairs.
    • Please insure the package for the total value of the contents and email us tracking information.
