The DELPHINE is an entry-level oboe model from RIGOUTAT, one of the three major oboe manufacturers. The upper and lower joint serial numbers match. It has the bell of the SYMPHONIE, a higher-end model. Accessories: Hard case from another manufacturer, joint cap for the lower joint (no joint cap for the upper joint) I received it about 4 or 5 years ago, but I haven't had a chance to use it beyond test playing. I replaced some pads last summer, and it's ready to play. It has fewer keys, making the instrument lighter and easier to play. Perhaps thanks to the SYMPHONIE bell, it produces a good sound. As shown in the photos, it has features like low C♯-H trill and left F keys, making fingering easy. It also has a third octave key. I was able to play high G. The intonation is normal. (F# and G# tend to be a bit high...) I feel it's within a controllable range. Made of grenadilla wood. I can't see any cracks. Thank you for the many "likes." I accidentally deleted the listing while editing the price and am relisting it. In my personal opinion, I think it's best for beginners to start with an instrument from a reputable manufacturer. RIGOUTAT is said to have the lowest failure rate. How about it for beginners or for use as equipment in a musical group? No returns or exchanges. Thank you for your consideration.
