这个Hacker News帖子讨论了一款开源口琴弯音训练应用“Let's Bend”。这款应用会以可视化的方式显示音高和弯音目标,帮助演奏者提高技巧。 早期评论中,一些经验丰富的演奏者建议专注于听觉和感觉弯音,并推荐了Gindick的书和Jason Ricci的YouTube频道等资源。他们强调直觉比精确度更重要,尤其是在布鲁斯、摇滚和乡村音乐风格中。 后来的评论则赞赏该应用包含了超弯音目标,并建议加入频率-时间图来追踪进度。其他建议包括该应用为初学者提供“弯音”的定义。帖子还探讨了其他口琴调音方式,例如Melody Maker,这种调音方式可以让演奏者无需弯音就能演奏大调音阶,并讨论了初学者的技巧,例如从塑料口琴开始。一位用户推荐了“Bending Trainer”这款应用。

For beginners, bending notes on a harmonica is a big hurdle. It requires a lot of time through regular practice. By bending, even the semitones can be sounded on the harmonica through special drawing and blowing techniques, which cannot be reached by regular playing of the channels. Beginners ask themselves, "Is that bending now or is the semitone exactly hit?"

The lean and performant Lets' Bend app makes it easy and fun for anyone to master the art of bending. By visualising the notes you play, you'll be bending like a pro in no time.

A short video about the functionality is published here:

The original idea in developing the Let's Bend app was to create an application that is available on all common operating systems and whose application window scales well. It is not uncommon to have other applications open while practising or to want to use the programme on different devices. Last but not least, all keys and the most common special tunings of harmonicas should be supported.

As a result, there are now two versions of the app. A desktop version for the operating systems macOS, Debian and Windows, and an Android version for mobile devices.

The Android version is published free of charge and without advertising on Google Play, Amazon and F-Droid.

Since a publication on Microsoft Store and Apple App Store is associated with additional development costs that exceed the financial effort of a hobby development project, the desktop version was not published there. Instead, here is an alternative download option for the desktop version.

As a preview, there is a web version available here.

For detailed instructions, check out our User Guide.

The source code of the applications is published here.

If you would like to support the developer of Let's Bend by making a voluntary donation, there is a Buy me a coffee function in the desktop version. But even here, Let's Bend remains free of charge.

But enough talk now. Let's Bend!
