Choosing a Grover Triangle: Material, Size and Support

Choosing a Grover triangle for orchestral percussion starts with three separate questions: which construction are you considering, which nominal size fits your needs, and how will you suspend and reach the instrument? The model name alone cannot answer all three.

This guide compares four documented families of concert triangle and the exact references listed below. It is a buying framework, not a personal sound test or a ranking. For the separate question of implements, use the triangle beater choice guide, which includes a listening comparison and a Grover beater shortlist.

Four Grover triangle families: what actually differs?

Super-Overtone: TR-5, TR-6 and TR-9

Grover’s Super-Overtone range has a Kanigen coating. Thomann identifies the underlying material as high-carbon steel. The documented nominal sizes are 5, 6 and 9 inches: do not infer a complete sequence of sizes from the model numbers.

This is a construction option to compare with the bronze families, not evidence that coated steel will produce the same result in every instrument, room or passage.

Bronze: TR-B-4 through TR-B-9

The Bronze series offers nominal sizes from 4 to 9 inches. Here, the B distinguishes the bronze family from the Super-Overtone references. It does not identify a beater: Grover’s TB-B implements are a separate tubular brass range.

The exact bronze alloy should not be inferred from the word bronze. Compare the documented instrument rather than assigning it the properties of an unspecified alloy.

HammeredLite: TR-BHL-4 through TR-BHL-9

Grover describes HammeredLite triangles as lightly hand-hammered in a random pattern. The documented nominal sizes run from 4 to 9 inches.

The surface treatment distinguishes this family in the catalogue. It is not an independent guarantee of a warmer, louder or more suitable sound for your repertoire.

Pro Hammered: TR-BPH-6, TR-BPH-7 and TR-BPH-8

For Pro Hammered triangles, Grover specifies full-surface hammering and individual serial numbers. The documented sizes are 6, 7 and 8 inches.

These are verifiable construction and identification differences. The manufacturer’s positioning of a range does not make it the automatic first choice for every player or passage.

Triangle size is not bar diameter

The inch figures below are nominal instrument sizes. They are not the diameter of the metal bar and are not beater-head diameters. Keep those measurements separate when comparing product pages.

A larger nominal triangle is not automatically a better orchestral triangle. Check the space available around the instrument, your access to it and the suspension arrangement you intend to use. If you can try instruments, let your musical requirements guide the final decision rather than treating the largest model as a necessary upgrade.

Listing discrepancy: the Thomann TR-9 page contains a conflicting 5-inch subsection heading. Grover identifies TR-9 as 9 inches; that is the nominal size used here. Confirm the reference with the retailer if its listing remains inconsistent.

Exact models and sizes: one comparison table

Each row below is one triangle reference, not a set of several triangles.

Suspension, support and access: check before buying

Treat the instrument and its working setup as related but separate purchases. Before ordering, make a short list:

• Suspension: what loop or holder will you use, and does it leave the instrument free of unintended contact?
• Support: will you hold the triangle or mount it? Check the actual holder, clamp and stand arrangement rather than assuming universal compatibility.
• Access: can you reach the playing area and damp the instrument without colliding with nearby equipment?
• Transport: what protects the triangle between rehearsals, and will the proposed case fit the reference you choose?
• Package contents: are the required holder, clamp, beater and case explicitly listed for that exact retailer reference?

Grover documents a triangle case, but a manufacturer’s case description is not proof that every retailer package includes the same accessories. Do not infer a clamp or beater from a photograph of a complete setup.

These are practical checks to make with your own equipment, not measurements of any product’s acoustic behaviour. For organizing an entry within a larger setup, see preparing an orchestral percussion entrance.

A smaller, clearer shortlist

Start by identifying the job the instrument must do and the equipment you already have. Then choose a few relevant construction and size alternatives. Buying all four families is not a substitute for a defined need.

Once you have an instrument candidate, return to the triangle beater comparison and observation sheet. That existing guide addresses attack, resonance and musical context without assigning a universal winner from catalogue specifications.

Short FAQ

Which Grover triangle is best for orchestral playing?

There is no single answer established by these specifications. Compare construction, nominal size and setup requirements, then evaluate a candidate in your musical context. This article does not report a comparative sound test.

What is the difference between HammeredLite and Pro Hammered?

Grover documents light, random-pattern hand hammering for HammeredLite and full-surface hammering plus individual serial numbers for Pro Hammered. The documented size ranges also differ: 4–9 inches and 6–8 inches respectively.

Does buying a triangle include its beater and holder?

Do not assume so. Check the package contents for the exact model and retailer listing, including any case, beater, holder or clamp you need.

Is TR-9 a 5-inch triangle?

Grover identifies TR-9 as nominally 9 inches. A conflicting subsection on the retailer page is not used as the size specification in this guide.

Sources and scope

Product references and technical documentation were checked on 21 October 2026. The linked Grover family pages are the primary sources for their ranges and construction descriptions; the linked Thomann listings identify the exact retailer references. Current prices, stock and delivery are not fixed here. No purchase or commission-attribution test is reported.

This guide separates documented specifications from suggested checks. It does not claim that I own, have tested or recommend every model listed, and no catalogue description is presented as a measured musical result.
