弾き始めは金属音が強いですが、弾き込むと柔らかくなってきます。弦自体が柔らかいので、冬はよく伸びます…

Nonostante sia un neofita apprezzo molto la qualità di queste corde che montate tra l'altro su un violoncello Basic lo migliorano molto. Senza parlare poi di poter suonare con accordatura di quarta,essendo nato come strimpellatore di chitarra....

Again, these are only for “bass tuning”—and for that they are great. They are not for classical but good for jazz. The E (low) is the only string I’ve found with correct tension. Helicore are popular on the low strings in regular tuning as well. I have found that other types of conventional strings can be used for the high strings, such as stark/heavy solo Perpetual “a” as the G string. And the D strings are the same for both tunings. Or, you might like the whole set. Great value.

This is just a correction on one of these customer reviews. The G string is supposed to be thinner than the D string. It's meant to be the first string of the cello. This strings are for a different tuning in fourths, like the four lower strings of a guitar, they are not for standard cello tuning. Make sure you read the description folks.

Ottimo suono, sia pizzicato che con arco, bilanciate. Lo strumento risuona molto di più che accordandolo Mi La Re Sol con le corde tradizionali.Spedizione Amazon ottima come sempre.

I've been playing a 'cello tuned in fourths around 25 years. I used to use regular Pirastro strings, risking high tension on the 'cello (especially on the low C, tuned up a major 3rd!). These new Helicore strings are a revelation. It's lovely to have a reasonable tension back on my 'cello and they play and sound great. I've been recording with them and love the way they respond. They're quick to speak and tonally rich. I'm so grateful that D'Addario make these, after all they can't be that big a seller can they? As far as I know they're the only set of 4th's tuning strings available, so they really have cornered the market...not that it can be a very big market :) I paid £105 for them and delivery from Amazon and was within a few days. Highly recommended.
