As part of my new routine of back-to-basics practice, I've spent considerable time working on my alto trombone intonation and sound. This journey has focused heavily on my Yamaha YSL 671, a model I've grown to appreciate for its versatility and responsiveness. One particular note has caught my attention: the G (top line of the alto clef). This note, often a challenge for alto trombonists, has served as a focal point for my exploration of this instrument's capabilities and the nuances of its design. This article will delve into my experiences with the Yamaha YSL 671, exploring various aspects from its intonation characteristics to maintenance and suitable mouthpieces, drawing on my personal practice and research into used Yamaha YSL models, Yamaha Alto trombones from the 2000s, new old stock (NOS) instruments, and the overall Yamaha YSL lineage.
Intonation Challenges and Solutions on the Yamaha YSL 671
The G on the top line of the alto clef, a high note for the alto trombone, often presents intonation difficulties. On my YSL 671, I found this note to be slightly sharp in certain registers. This isn't necessarily a fault of the instrument but rather a common challenge with alto trombones in general, stemming from the instrument's shorter tubing and the physics of sound production at higher frequencies. My approach to resolving this involved several strategies:
* Embouchure Adjustment: Fine-tuning my embouchure was crucial. A slight adjustment in the aperture and air pressure allowed me to subtly flatten the G, bringing it into tune. This required patient experimentation and a keen ear, focusing on the subtle changes in my embouchure's shape and airflow. I found that a slightly more focused and centered embouchure helped to control the pitch more effectively.
* Slide Position Refinement: The precision of my slide positions, particularly in the higher register, played a significant role. Even minor discrepancies in slide placement can drastically affect intonation. I meticulously checked my slide positions against a tuner, making tiny adjustments until the G was consistently in tune. This process highlighted the importance of developing a precise and consistent slide technique.
* Mouthpiece Selection: The mouthpiece significantly impacts intonation. While I'll discuss mouthpiece choices in detail later, experimenting with different mouthpieces allowed me to find one that optimized the intonation of this challenging G. Some mouthpieces might inherently favor certain notes, and finding the right match for my embouchure and the YSL 671 was key.
* Valve Alignment: Although less directly related to the G specifically, ensuring the valves on the YSL 671 are properly aligned and functioning smoothly is essential for overall intonation across the instrument's range. Any sticking or misalignment can introduce inconsistencies that affect the accuracy of all notes, including the higher register.
Yamaha YSL 671 Alto Trombone Tuning: A Deeper Look
Yamaha YSL 671 alto trombone tuning is a multifaceted subject. While the instrument is generally well-regarded for its intonation, achieving perfect accuracy requires attention to detail. Beyond the G, I also focused on the overall tuning across the instrument's range. This involved:
