<p>It depends. It seems like there might be a bit more of a personal friendship/mentor relationship rather than purely a professional accompianist here, but I may be reading more into it than there actually is.</p>
<p>A straight professional relationship normally covers all the discussions about money upfront, including expectations for meals, travel costs and travel time. (Some have a straight hourly fee time of travel, some for time above a predetermined mileage radius). If the relationship is strictly professional, I'd ask, or contact him tomorrow and ask what is owed for travel time.</p>
<p>Where it may get sticky is if the accompianist is a personal friend or mentor. While he might want and expect his fee for the actual service, he may feel close enough to give his travel time as a gift, or may even be affronted if offered any money for his services. You and son should have a pretty good read on the relationship if one exists.</p>
<p>A couple of personal experiences for reference:</p>
<p>For son's on-site (and one recorded submission) auditions, while I was willing to pay all including travel, I had a previous (non music) professional relationship with his accompianist. We actually bartered services, mine for his. It worked out very equitably, and all parties were happy.</p>
<p>The one accompianist my son used exclusively his last two years as an undergrad for juries, recitals, and grad prescreens worked with him quid pro quo, again bartering services, his when she needed string accompiament. (See my #10 post above; she never cashed his check, and returned it with a graduation card.)</p>
<p>Son's local chamber coach took him into NYC instrument shopping, at our request. I fully expected to pay her hourly rate, and was quite willing to do so. When son said I had given him a signed check, and he just needed to fill in the amount her response (in heavily accented Russian) was "Tell your father he is idiot... he gives me great insult!" She even offered to buy lunch, but relented when son said he would not eat if she paid. </p>
<p>I think the actual travel ticket costs, lunch (and dinner if necessary) should be paid, in addition to all fees. Ask about his travel time, and see. If he says don't worry, I'd still follow-up with a gift certificate at a local restaurant.</p>
